[Q] Reading value from registry

Hello,
I'm new to prgramming with C# and wanted to know how I can read a value from the phone's registry and display its data in a TextBox on WP7?
Thanks

The problem isn't C# per se, but the public phone API doesn't allow registry access. If you only need read support, there's a library out there that will give you read capability on most of the registry, though you won't get write (permissions issue). Write surrport is also available on some devices, though that gets... tricky.
One place you can find this library, along with an example of how to use it, is in my IE Search Switcher app, located on this site. The short version is you include the native.dll library, enable some optional application capabilities, use the phone's interop library to get COM import into C#, and import the nativle library using COM. You can then call them from the managed (C#/.NET) code.
The Homebrew library comments and and included readme should explain enough to get you started. Be aware that any app doing this will fail Marketplace certification; you'll only be able to distribute it to people who have developer-unlocked phones.

[WORK IN PROGRESS] XML Provisioning for all devices...

At the moment I'm working on an app called "WP7 Root Tools". I got the registry editor almost finished, but I am also going to add a File Explorer, Certificate Stores and maybe more. When the registry editor is working I will release the first alplha-version. As the title of the app implies, the tool uses root privileges to perform queries and transactions. I let the tools parasitize other processes to get the code executed in the TCB chamber of the device. I have this working stable now on my Samsung Omnia 7. Unfortunately I have to use a little bit of device-specific API's to do this. And I have to make quite a detour to make it work, which has a negative impact on the performance.
So the ultimate goal is that, in the end, this will work with other, more direct API's, which work on all devices. During my research I found some possiblities that need more investagation. I already decided that I will first concentrate on getting this working with my Samsung device, so that I have at least the tools to do further research. But I thought I'd drop some of my findings here that may lead to better device-support and better performance for future-versions of the tools.
There are many ways that may lead to executing code with elevated or root privileges. But in this post I want to concentrate on XML provisioning. A lot of info can be queried and configured through these API's. I have tried to call the native OS functions for XML provisioning. The function you need to call is: DMProcessConfigXML(). And it is declared in: Cfgmgrapi.h. If you call this function it returns errorcode: 0x4ec (or 0x800704ec), which means "Access disabled by policy". If you use a native COM dll and you forget to add ID_CAP_INTEROPSERVICES to the WMAppManifest.xml, you will get the same errorcode when calling a native function through the COM-interop. So when I get the same errorcode when calling DMProcessConfigXML() this may suggest, that I might be missing a capability in the WMAppManifest.xml.
In another thread on this forum some undocumented capabilities were discussed. One of them was ID_CAP_WAP. Since OMA Client Provisioning is also call WAP-Provisioning, I thought that might be the missing capability. I was not able to add the capability from within Visual Studio, because the capability is missing from the corresponding xsd's so it will give an validation error on building the project. But I could add it manually after the project was build. When I deploy it to the device, using the Application Deployment tool, it would return "Access is denied". I thought it might be an invalid capability, but when I changed the capability to ID_CAP_XXXXXX that would return "Install failed. Fix the capabilities." which is the real error message for an invalid. That implies that ID_CAP_WAP is in fact an existing capability, but I'm just not allowed to use it. When I would be able to use it, I would probably have access to the function DMProcessConfigXML(). That part of the app would be impesonated into higher chambers.
So the big question is what is keeping me from using the ID_CAP_WAP? Why am I not allowed to use it? I tried to attach a debugger to XapDeploy.exe, but it does not throw any exceptions at all. The errorcode is generated in the phone. Getting this fixed will give a big boost to getting closer to root access on all devices. Any help or insight on this will be appreciated.

I sent some tweets to da_g, chris, chevron, julien schapman, and a few other devs to let them know this is going on...I'll try tom hounsell too he may know a bit more about this
I'm notifying notebookgrail too because he has been doing some work with dell venue pro devices
Good luck

At a wild guess, it's probably looking for a signature. Using signed code for trusted functions is the kind of thing MS likes to do. :-/
All that said, if you have ProvXML working on Samsung, I would *love* to take a look at it. I'm maintaining a cross-platform Homebrew library. Currently I have at least partial ProvisionXML on HTC and LG, but none on Samsung. I don't have a Samsung device to test with, which is making it hard to try things out...

ID_CAP_WAP isn't a capability you can assign yourself. A higher up has to assign it to you.

Well, the whole ProvXml stuff will become irrelevant, when I finish the tools. Because ProvXml is not really user-friendly and my tools will provide that functionality in a user-friendly fashion. So at this moment I want to concentrate on finishing the first alpha-version. Later on, I will probably clean-up the code and release it. But it's quite complex, because I added async multithreading to keep it all smooth.

Thanks for this info. But what I read from this is that you just need to be able to impersonate. Has anyone tried CeImpersonateToken() with this SID?

Abstraction of the ProvXml capabilities is awesome, assuming that we can fully use them and/or extend them if needed. It's useful for a ton of stuff. I've written a small amount of abstraction for registry writes and such, but having the full functionality exposed through a clean API would be fantastic.

[Q] WP7 and native for beginner

Hello everybody,
I got a WP7 Samsung Focus and I want to port my old application to this device and join native forces for WP7
My plan is simple: I'll convert my app into a dll, rewrite new gui in C# (or whatever the way to do it on WP7). I saw multiple posts about calling native code (original from Cris Walsh: http://goo.gl/2Tjks). Then I saw a few posts mentioning that it's impossible etc etc.
So, a few questions:
0) can I do it for my app (I don't need marketplace exams etc, I don't care for that)? I know that some WinAPI could be unavailable/broken, all I ask at this point if it's possible to load and run native dll without changing or re-flashing ROM.
1) ms wants 100$ out of my pocket to be able to deploy to my own device (WTF?!). What can I do to deploy to my phone without paying the crooks? (VS2010 tell me to register there and registration askes for 100$).
2) Is there a sample project I could D/L and run, I have zero experience in C# and I have no idea how to load and call native DLL from managed code in WP7? All these half broken samples are totally useless to me, I simply wanted to working HelloWorld app that loads and runs simple dll.
thanks

0) Yes, what you describe is possible. There are lots of limits, though - WP7 applications have very low permissions, and calling native code doesn't fix that. Unless you need to edit something outside the app's own iolated storage, though, you're probably OK.
1) Aside from the official marketplace account ($100), there are a few options:
a) if you've got an LG phone, they come with a built-in registry editor that can be used to dev-unlock your phone. I forget the exact key you need, though.
b) if you've got a student email address (ends in .edu) you can try registering through DreamSpark. This is free.
c) if you don't mind rolling back to pre-NoDo (7004 or 7008) you can use ChevronWP7 Unlock (instructions available on this forum). If you don't have a restore point that far back you can flash an official ROM for that version.
d) if you don't mind waiting, ChevronWP7 Labs will be available at some point (no ETA that I've seen, but it's been talked about for months) and will provide dev-unlock (but not marketplace account) for a nominal fee.
2) There are lots of apps distributed with source, and most of them will use some native code. You could do a search on this forum for subject lines including the tag "[SOURCE]" and find several (I release source for all my apps). However, I suspect what you'd find most useful is Heathcliff74's guide to WP7 apps that use native code, which is on this forum at http://forum.xda-developers.com/showthread.php?t=1299134. It includes step-by-step instructions.
Hope that helps! I look forward to seeing your app. Also, don't hesitate to ask for help with the actual development; I suck at GUIs and Silverlight but am fairly proficient at C# if you need somebody who knows that language, for example.

There is an ETA for the new ChevronWP7 unlocker:only a few weeks away from launch!

At this point I want to make a DLL from my simple app and call a few functions that interact with filesystem and network. FS is needed only for simple stuff (loading config file etc) from installation folder and creating some temporary files for local storage. Network is tcp/udp, I guess network should be available.

I did some search, it seem that I've done that part. Chevron dev unlock was pulled out from their site, but the old version remains scattered all over the board. There is a good thread a good thread on how to do it. It happens that my phone is 7004. Where can I get old ROM in case if something goes bad and I need to re-flash? Is it easy, am I risking to brick and loose my phone?
I just tried to run sample phone app and it runs on the phone. Initially it said that it was revoked by MS, I run dev-unlock one more time and now it works.

I'll try to search, hope I'll be up and running soon. Too bad WP7 is DOA. They always had much better tools than all these ghetto Symbian/Android/Xcode crapware tools... WTF is wrong with these guys, at the point when they were surpassed at speed of light by newbies iPhone and Android they made some backward steps to cut off most of the devs (but they added all these 500K Silverlight newbie devs...). I'm so disappointed with Android, seems like they hired all these retards who were fired at symbian: same **** tools

I downloaded a few samples and it seems that all of them contain prebuild dll's and all of them are COM dlls or something like that.
What I'd like to find is simple sample that contains src code to native WinMo dll and C# project that it uses.
As far as I know native dll cannot be build with latest tools (am I right?), but I can use cegcc or VS2008 to build native DLL's.
stuff like:
Code:
if (ComBridge.RegisterComDll("ComFileRw.dll", new Guid("EEA7F43B-A32D-4767-9AE7-9E53DA197455")) != 0)
is totally unknown to me. I would really like to avoid to even elarning anything about COM related stuff. I prefer not to mess up with code that isn't portable.

HI mtlgui,
unless Heathcliff finishes his WP7 Root Tools SDK, you don't have any other way to access native c++ code besides using COM. DFT (The DarkForcesTeam) released a firmware loader, that allows you to flash customized unsigned firmware. They were also able to do some native c++ coding with the WM API. However the used firmware for that is not public and it is limited to HTC devices.
Did you already consider to write your application in c#? Mango has now TCP/UDP socket support for outgoing connections. Incoming connections or services running on the phone aren't possible without using native code, at least for the moment.

Hi rudelm,
if the only way to use native is to build COM dll, then I'm OK with that. My app code is old and I'd rather throw my WP7 device to trash can than trying to rewrite my app in C#.
Eventually, down the road while hacking maybe I'll learn c# well enough to do anything with it other than GUI and calling native/COM dlls.
So, just to confirm my understanding. I need to write COM dlls that access native API (socket, filesystem, wavein/waveout etc) and then load these COM dlls and call their functions from C# (or whatever is the closest lang to c/c++ in the WP7 world).

@mtlgui:
You've pretty much got it. A few thoughts, though:
There is a webserver project available on this site. It includes source for its C++ native component (the library is called NativeIO; I can probably send you the source if you can't find it). It exposes registry, filesystem, and TCP server and client sockets to COM. Note that because this library was built for pre-Mango phones, just compiling it and shipping it may not work on Mango phones as many deprecated libraries were removed in Mango and if the DLL contains any references to them, it won't load.
Generally speaking, what you're asking for with TCP/UDP is possible, though you may have to code against the winsock API directly. It sounds like you're doing as little as possible with C#, so even if the Socket API that is available with Mango were sufficient for your app's needs, you wouldn't be using it.
Filesystem access... even if you have read access to your app's install folder (I haven't checked, though you should), you almost certainly won't have write access. Each app does have a writable "isolated storage" though, under \Applications\Data\{GUID}\Data\IsolatedStore\. I've only ever tried writing to it using C# though, so I don't know for sure if it's writable using the native APIs directly (should be, though).
It's probably perfectly OK to write your app as one big native DLL (hell, it *might* work to just change the build type from Application to Library, then rename main() or something like that). You will need to expose the library to COM, but that's easy. You can then write a very simple C#/Silverlight app (see Heathcliff's instructions, or just post the COM interface and soembody could write it for you). All the C# app needs to do is use ComBridge to access the native DLL, and call a "run()" function or something similarly simple.
For what it's worth, C# is very close to a superset of C++, at least on the desktop. The phone version is crippled a little by not allowing the use of pointers - everything has to be done with strongly-typed references instead, which can make network code a little annoying but is otherwise rarely a problem - but with a little experimentation you may find your disdain for C# to be misguided. It's a useful language to know it today's job market, if nothing else.
Why is your phone still on 7004? That's the launch retail build, something like eight months out of date. On the plus side, this means that things like ChevronWP7 Unlocker still work for you, as you found. On the minu side, it means you're putting up with bugs and missing features that you needn't be. Have you tried updating at all? If/when you do update, make sure to back up the restore points that the Zune software generates (they got in %localappdata%\Microsoft\Windows Phone Update\). That way, if you ever need to roll back to 7004, you can do it. Normally, only the most recent restore point is kept.
Flashing ROMs is safe so long as you don't try something like flashing the wrong one for your device. Unless your bootloader is unlocked (only possible on HTC), you can only flash official ROMs anyhow, which saves you from most of the risks. On the other hand, you're already on as old a ROM as you will find, and so long as you keep your restore points, you can return to it any time you want to, easily.

I'm googling now the board to find NativeIO and that webserver app. So far only references to it, but no src code.
I'm ok with isolated read/write access. All I care is persistent fs storage.
My phone is still 7004 because I just bought it so I can do some WP7 development. I don't want to mess up with updates at the moment.
As I understand from another post ComBridge is C#->COM->native c++ dll or any other dll that can be used, right? I'm just learning some COM to learn enough to start actually programming for the phone. I see that I can pass whatever data I want, but I don't seem to be able to see a way to register callbacks so that native/COM could call back to C#

[XAP] [Source] [Mango] Webserver

Webserver (for Mango)
Webserver is now supported for Mango devices!
During NoDo this tool was used much for exploring the "\Windows" directory, but when Mango came none could explore it.
There is probably many new things to find in the new OEM Mangos (that could not be extracted till now (Exception's: ROM dumps))
Source code is available in attachment and should build without any problems (except for the dll reference)
- Follow stem 6 for Microsoft.Phone.InteropServices.dll errors
Install XAP => Navigate to the phone's IP shown in application => Browse and enjoy.
- Change password on first launch (its randomized)
Many thanks to davux for creating the base for this tool.
- Orginal NoDo thread Here
Changelog:
v0.1 - Initial Mango version release
v0.2 (iconizer)
- Thanks MarysFetus aka Suicide Clown for the great icon set and start screen, love em
- Many thanks to GoodDayToDie for informing me that this app can / and will run from now without the <"ID_CAP_INTEROPSERVICES">
- Removed old OEM dll's that where not used (xap size: 812 KB => 250 KB)
//fiinix

Nice works my friends... I Like It
Thankx

@fiinix:
Thx for porting the webserver to Mango !
As I remember the initial version from Davux had an on device execute feature.
Do you plan to implement execute feature ?
Could be very useful for exploring all .exe files in the windows folder.
Greetz
contable

Freaking awesome, man!
One suggestion: I don't believe this app does anything that requires ID_CAP_INTEROPSERVICES (that is, it doesn't need to open any driver handles). I may be mistaken about that, of course. If it doesn't, however, there's a real benefit to removing that capability as people with interop-locked phones could then run it. Note that the library used may try to do things requiring interop even though the app doesn't need it to.
In addition to its uses as a hacker's tool, I also want to point out that this app can be used to store files on the phone for easy transfer between computers. It's less convenient than true USB Mass Storage, but it works (even if you don't have the USB cable with you) so long as there's a WiFi access point that the phone and PC can both connect to.
Oh, and by the way, this app will run happily in the background if you use JaxBot's no-dehydrate hack. You can do other things then, even browsing the webserver from the phone's own browser! Of course, it will also use some resources.

Now slimmer, and no ID_CAP_INTEROPSERVICES
OK, this is just a modification of the XAP file - I didn't even recompile the source (thank you so much for including it, though!)
Things I did:
Removed ID_CAP_INTEROPSERVICES from the AppManifest. This will allow the app to be installed on interop-locked phones. It wasn't using it anyhow.
Removed the OEM-specific DLLs that are only useful if you have ID_CAP_INTEROPSERVICES. They weren't being used, but they made the download and install bigger.
Result: A smaller app that works exactly the same and can be installed on any Dev-unlocked Mango phone.

Really neat. Mind if I design some sort of decent icon for this app?
Regards, Suicide Clown
//Update:
finished the Icon:
Hope you like it.

The "NativeIO_Mango.dll" is actually a communicator for "Homebrew.csproj" containing COM+ "IWinSock" and "IFileSystem"
- Homebrew.csproj exists in this projects code.
The battery interop will not talk to NativeIO_Mango.dll (the "Webserver" will tho)

Filesystem.dll is not used anymore in Mango version (its a NoDo dll)
"Thanks so much for your great libraries."
- Thank you so much

I could swear it didn't work without the filesystem.dll one time I tried haha. I guess that was something else
Thanks~

perfect! Now we'll look for regedit editing & file transfering. Any ideas?

Fiinix this is just amazing work! Because of you, I've need to rewrite a chapter of my thesis
Let me ask some questions regarding the supplied source code:
There are four folders inside the rar archive:
The Lib folder contains all OEM DLLs from Samsung, HTC and LG.
The Homebrew folder contains all old code from davux that is necessary to open up the sockets, files and registry entries (if needed?)
NativeIO_Mango contains your altered native DLL that can be used under Mango
The Webserver folder contains the actual WP7 application, that glues everything together into one nice app.
From the underlying workings:
Davux tried to build an API that resembles C# Sockets from the desktop. This way the C# Webserver project of jgauffin can be reused in the WP7 application. You removed from Davux's NativeIO project the references to all parts that require the native OEM DLLs (which is why GoodDayToDie stripped the unneeded DLL files and removed ID_CAP_INTEROPSERVICE to allow users without interop-unlock to use the app).
If this is so far correct, I'm wondering how some things in this application could work:
Ok, so you've removed the code that allows access to the filesystem and registry which uses the native OEM DLLs. How is it possible, that this application can access folders outside its Isolated Storage??? The application should not be allowed to access the windows folder nor any other folders? I know only of one folder, that should be read/writeable. Its a folder that heathcliff found in the policies, I think it was some kind of log folder. Or is readable access with WM6 native API to all files possible?
In WMAppManifest.xml stands ID_CAP_NETWORKING. This is necessary for navigating between different XAML pages but also necessary if we want to do something with the native network access. Can this capability removed or will the application break?
To sum up, if these assumptions are all correct, the policy system is partly useless from the moment on, where someone is capable to call native code, that does not require ID_CAP_INTEROP. This would theoretically allow a submission to the Marketplace?
Right now, I'm heavily confused and irritated, please explain me my error in thinking
PS: I tried to build the NativeIO_Mango project. I changed to release target and build. However, it exits with error message regarding the missing _CE_ALLOW_SINGLE_THREADED_OBJECTS_IN_MTA setting. I've added it, but then I get 19 more errors. Each time it is unresolved external symbol.

Hi Rudelm,
I can't answer exactly what Fiinix did, but I can resolve a couple other points for you.
The OEM DLLs allow higher-than-normal app permissions (breaking out of the low-privilege "sandbox" that apps normally operate in). However, there are a few parts of the filesystem that can be accessed even without them, by design. One of those is the Isolated Storage for the app, which obviously needs to be readable and writable by the app. Another one is the install directory, which only needs to be readable so libraries and resources can be loaded (the webserver app doesn't allow you to browse this folder, but I'm confident that it could if it was coded to). The third is the Windows directory, which is also read-only (and many files and folders within it can't be read) but is similarly required because the app needs to be able to load system libraries (including the TaskHost.exe binary that hosts the app DLL). "Normal" apps can't access these folders simply because the Silverlight API doesn't have a function to open or list an arbitrary location on the filesystem (only within the isostore, which it abstracts the path to).
I don't know what happens if ID_CAP_NETWORKING is removed. It's quite likely the app would break, since that capability may be checked any time the app tries to open a socket (directly as this app does, or indirectly via the Silverlight APIs). You could experiment and do some research to find out, though. It would be interesting to see.
I wouldn't worry too much about apps in the marketplace running amok with native code (even in the low-privileged process, they could still do some harm). The ComBridge Silverlight API that is required to access native code at all is prohibited from use by independent software vendors - only Microsoft and their partners are allowed to use it for Marketplace apps. Somebody tried submitting a Homebrew app to the marketplace (another opportunity for some research, if you'd like to find out more) and discovered that the use of ComBridge is detected and blocked during the submission process.

There we go, a enchanted new version v0.2
- Optimization's from what everybody has told, the best from all worlds

thanks for the explaination!
It seems like a plausible idea that the native code and the WP7 app needs to access some of the folders to work. So the silverlight managed code won't grant access by design to the Windows folder. Can you tell me where this folder for the installation packages is?
Regarding the capabilities: I've checked it with the marketplace capability test tool:
Result Details
[INFORMATION] : Capabilities used by application :
ID_CAP_PUSH_NOTIFICATION
ID_CAP_NETWORKING
ID_CAP_IDENTITY_DEVICE
I've removed ID_CAP_NETWORKING and it immediately stopped working. No dialogue that shows the IP address, only username and password. That is at least good to hear
Regarding the marketplace certification: You could be right, I've also read somewhere that COM is only available to some third parties like Adobe and manufacturers. Maybe I try to submit a little test app that uses interop.

Why the ID_CAP_NETWORKING is needed is because of the WP7 policy system; ID_CAP_NETWORKING allows usage to those resource locations:
Allowance to "WINSOCK", windows socket API
Code:
<Rule Description="Authorization rule for capability ID_CAP_NETWORKING" ResourceIri="$(GLOBAL_RESOURCES)/WINSOCK/CONNECT" SpeakerAccountId="$(SYSTEM_USER_NAME)" PriorityCategoryId="PRIORITY_STANDARD">

"Can you tell me where this folder for the installation packages is?"
\Applications\Install\9bfacecd-c655-4e5b-b024-1e6c2a7456ac\Install\

Nice, thanks for the policy entry. Where did you find it?
Regarding the installation path: I thought you ment a special path to the place where the compressed xap is deployed or something like that before installation. But now it is clearer to me why the application is able to access Windows, installation dir and isolated storage
I've tried to upload a small app with native code but as GoodDayToDie said, the marketplace will see that it contains access to native API and that my account isn't allowed to do that.
So the world is safe again, I'm calmed down now hehe

The policy is from a ROM dump: BasePolicy.xml (Currently got "WP7 Mango Build 7661" dump), i think its this one i downloaded: [DUMP]WP7.1 Build 7661 "Mango"
Some more clearance: \Applications\Install\{ The application Guid }\Install\
- Each application has its own isolation storage:
\Applications\Data\{Guid}\Data\IsolatedStore\

I don't know if it's possible but can you add access to /My Documents?

Sorry to say but the basics of this app allows only access to \Windows (dll reference location) as used for extracting of xap files, xml and dll (reverse engineer). You will probably need WP7 Root tools.

Include local JavaScript within PhoneGap on Windows Phone 7

I have a PhoneGap application designed to work on multiple mobile platforms. I'm loading a dynamic HTML content from an external page on the Internet using jQuery Mobile. The problematic system is Windows Phone 7.
This is what I get from the external page, with the URL of the script tag already replaced to load from the phone instead of from the net to save bandwidth:
HTML:
<script type="text/javascript" charset="utf-8" src="x-wmapp1:/app/www/test.js"></script>
This works fine on Android, iPhone and even BlackBerry when I replaced the x-wmapp1: part by a respective counterpart (e.g. file:///android_asset/www/ on Android). However, on Windows Phone 7 it doesn't seem to work at all.
When I try to load the same URL via $.getScript function, it always returns a 404 eror, even if I try and load it with a relative path only.
Any suggestions?

First of all, this type of question may be better suited to the Software Development or Apps and Games sub-forums, as a lot of the people who hang out here are more familiar with homebrew hacks. I'll give it a shot, though.
First of all, what kind of path are you trying to use? I haven't tried loading scripts or images in HTML or JS, but to dynamically load content within the app itself typically requires some care with regard to the path. For example, is the JS file being built into the assembly (as a resource) or included alongside it (as content)? How about the HTML page?
This is a kind of lame approach, but one option that's sure to work is just inlining the scripts in the page, directly. That won't increase the total app size or load time at all, although it might make maintaining the app take a little bit more effort.

Thanks for the reply, I will try to post this into the more appropriate forum.
With regards to paths - you can see the path in the HTML snippet I provided in the original question. It's all a bit specific and we cannot afford to load JS directly from page, since that does increase the size of the resulting HTML, sent from an external PHP page, thus increasing bandwidth. This is the first reason why we chose to have all JS and CSS files directly bundled with the application and load them internally rather than from Internet.
Also, all of JS files are included alongside the application as content. I'm using the same approach for all images, since if they were included as a resource, they would not show in the application.

First question: have you set the IsScriptEnabled proerty on the control to True? It defaults to False, preventing scripting within the control. Also, changing it only takes effect
on navigation, so if you already loaded the page and then set this property, it still won't work.
Anyhow, I missed that your HTML was coming externally, and only the scripts and stylesheets were local. That's... interesting, and seems reasonable enough, and I can't find any info online that exactly matches your use case. The way you're structuring the script src URI looks weird to me, but I haven't messed with the WebBrowserControl very much at all.
One solution, though a bit hacky:
Use the WebBrowserControl's InvokeScript function to dynamically load scripts into your pages. To do this, you would first need to load the script file content into a .NET String object. The GetResourceStream function is probably your best friend here, combined with ReadToEnd(). Then, just invoke the eval() JS function, which should be built-in, and pass it the JS file content. That will load the JS into the web page, creating objects (including functions) and executing instructions as the files are eval()ed.
Of course, you'd need to do this on every page navigation, but you can actually automate it such that the page itself requests that the app load those scripts. In your app, bind the script-loading function to the ScriptNotify event handler, probably with some parameter such as the name of the script to load. Then, on each page served from your server to the app, instead of including standard <script src=...> tags, use <script>window.external.notify('load localscript1.js')</script> and so on; this will trigger the app's ScriptNotify function for you.
I hope that helps. I can see your use case, but somewhat surprisingly, I couldn't find anybody else online who had either run into your problem or written a tutorial on doing it your way.

Thank you for your reply, it was very informative. One question though - why do you think the way I'm structuring the SCRIPT URI is wierd? I tried to mess around with relative URIs and the such, however those would load the JavaScript file from Internet rather than from the application itself.
The problem I'm running into with your proposed solutions, however is that:
1. the project is a PhoneGap/Cordova application, using its own components, so I have no idea where I would look for IsScriptEnabled here (although this all worked on an older PhoneGap release, so I'm guessing they have it set up correctly)
2. injecting a script programmatically on each navigation would require me to rewrite much of the code we already use for other platforms, not to mention those custom Cordova components, which I don't even know if they can handle such thing
As for my user case - I was surprised to be the only guy on the internet with this methodology in place as well. So it either works for everyone else or nobody really thought of doing it my way, since it's basically an Internet application (maybe the don't want to disclose their sources, who knows).

Of course you not "the only guy". I've tried to port/run a few HTML java-script based games on WP7 (Digger and couple more) more then year ago; they runs well with one HUGE exception - touch screen events are freezing scripts execution and make games not playable.

The "x-wmapp1:" URI scheme was what I was referring to. Not sure where that comes from, but I haven't done anything really with the WebBrowser control.
I have no knowledge of PhoneGap or Cordova; I assume they're "we write your app for you" frameworks? One would assume that such tools would know to set IsScriptEnabled, but you may have to do so manually. A bit of web searching on that direction may be fruitful - maybe earlier versions enabled scripting by default, and now it's disabled by default so you have to specify an option somewhere?
Injecting the script on navigation really doesn't require any major change to the server-side code. I mean, is sending
<script>window.external.notify('load localscript1.js')</script>
really much different from sending
<script type="text/javascript" charset="utf-8" src="x-wmapp1:/app/www/test.js"></script>
? If that's too different, you could instead send
<script src="http://yourserver.com/LoadLocalScripts.js"></script>
and put "LoadLocalScripts.js" on your server with the following code:
window.external.notify('load localscript1.js');
This has only a trivial increase in server traffic and load time, but lets you continue using external scripts instead of inline ones. Very little server-side change needed at all.
Now, the additional client-side code to support the window.external.notify and call InvokeScript... normally I'd say that's dead easy, because it is if you have any experience with the .NET framework, but in your case I get the feeling that this isn't so? I code to the framework, or to the underlying native code, and I tend to code "raw" (very little auto-generated code), so I'm not going to be able to help you solve the problems with a "make me an app" wizard unless I can see the code it generates for you.
For what it's worth, here's the approximate raw code that I'd use (it's over-simplified, but close enough):
void HandleNotify (String param) {
String[] parts = param.split(" ");
if (parts[0] == "load") LoadScript(parts[1]);
}
void LoadScript (String script) {
String content = Application.GetResourceStream(new Uri(script, UriType.Absolute)).ReadToEnd();
theBrowserControl.InvokeScript("eval", content);
}
void theBrowserControl_Loaded (...event handler args here...) {
theBrowserControl.IsScriptEnabled = true;
theBrowserControl.ScriptNotify += HandleNotify;
theBrowserControl.Navigate("http://yoursite.com");
}

the URI comes from Windows Phone itself, with this code, you can see for yourself:
var a = document.createElement('a');
a.setAttribute('href', '.');
alert(a.href);
also, I've been informed that this works in Cordova 2.0, so it might be a 1.8.1 bug... will try and see how it goes
thanks for your help so far!

Looks like it was a problem with PhoneGap 1.8.1 - after upgading to Cordova 2.0 (PhoneGap got renamed) it all works now... thanks for all the help!
