I can't deploy applications to to my Windows Phone 8 device from Visual Studio Express 2012 anymore. I always get the following two lines in the console:
Deployment of application to device failed.
The interface is unknown.
The emulator also does not work anymore (xde.exe just crashes). All that worked once (Hyper-V is active).
All that happened without a change to my app (the same happens with a fresh hello world app).
The problem is not my phone, I tested a different phone (even different model), same problem.
I already completely removed and reinstalled the Phone SDK including Visual Studio.
The problem might have occurred since I updated to Windows 8.1 but I am not sure about this.
If anybody has a clue of what is going on here I would highly appreciate your help.
Since you've already tried removing/reinstalling VS and SDK, try creating a new user account on your Win8.1 box and running VS from that. If it works, the problem was probably some settings in CurrentUser registry hive, which Remove doesn't always clean up. Reinstall the already-installed VS and SDK may work better.
The 'interface' error means this is likely some COM issue, and that implicates registry. If you can figure out which DLL contains the interface, you may be able to fix it with (admin command line) > REGSVR32 <dllPath>. You can trace the registry accesses being made when you try to debug the app via SystemInternals ProcessMonitor

So many things happened that I don't know where to start. Seriously, shouldn't this be simpler?
Edit: Someone here knows how can I contact Microsoft to tell this? Or even, can someone tell them about this problem?
I have the last Windows 10 desktop and also have Windows Phone 10.0.10512.1000. I installed Visual Studio 2015 with tools for Universal Apps development (and also 8.1). I have a Lumia 730.
So I connected my phone with my USB cable. Everything fine, the phone gets recognized and I can navigate through the folders.
Then I started Visual Studio 2015 and created a blank universal app. Compiled and tried to deploy. Now this is happening to me: Visual Studio hangs for some moments. Eventually I get an error telling that the device was not found (DEP6200).
I already tried dozens of solutions:
disconnecting from wifi in my laptop and my phone
restarting the IpOverUsbSvc service
rebooting the computer and the phone
deleting the devices in the Device Manager
Registering and Unregistering the phone (it sometimes works)
All of the above with the phone screen unlocked
disabling Hyper-V
disabling firewall
Other solutions that failed miserably
I also tried to use that Windows Phone Developer Power Tools. When I try to use it, it asks me to install some "Phone Tools Update Pack", but when I try, it says that the operation didn't succeed, and also shows the NRE message string (object reference not set to an instance of an object).
I can go through the phone's folders without any problem. I tried to reinstall the drivers... i tried everything.
It's quite sad.
Do you guys can think of some more thing to check?
EDIT: I tested this app before doing all this: https://blogs.windows.com/buildingapps/2015/07/09/just-released-windows-10-application-deployment-tool/
And it worked. If that's the case, is Windows Phone 10 deployment over Visual Studio working already or we have to wait some more time?
Edit2: After making some changes to my app manifest and choosing "ARM" config, now I get this:
1>Deploying to SD Card...
1>Updating the layout...
1>Copying files: Total <1 mb to layout...
1>Checking whether required frameworks are installed...
1>Framework: Microsoft.NET.CoreRuntime.1.0/ARM, app package version 1.0.23117.0 is not currently installed.
1>Framework: Microsoft.VCLibs.140.00.Debug/ARM, app package version 14.0.23019.0 is not currently installed.
1>Installing missing frameworks...
But it just stays there. It's stuck, and it stays there forever. At least I got some info... Its more or less the same steps that WinAppDeployCmd does, but the command line app does it successfully.
Somehow the problem got solved. I created a brand new project and did this:
1 - In your phone, try disabling the developer mode on your phone. What an unexpected development!
2 - Disable the "phone discovery" thingy. I don't know the name of this configuration in english (as my phone is in Portuguese). Just in case.
3 - Choose the correct architecture. This is obvious, right? In my case, ARM. If you try deploying with x86 or x64, it should give you an error. For me, it didn't.
From now on, you should be able to deploy your apps in both developer mode and non-developer mode. It just works, somehow. And it might NOT work for you, sorry. I think I got lucky.
It worked even after a reboot. So the solution is "pretty solid" (in an universe where gelatine is pretty solid).
I had the same problem. I tried the fix of the comment and went to devices manager.
Under USB-Devices there were three Lumia 920s listed.
I selected the second one and clicked on uninstall.
At the end it asked me to restart the Computer. I clicked on NO.
(When I uninstalled the first or third one, it didn't ask me that).
Then the error disappeared (now another common one appears (HRESULT: 0x80073CF6))
I have a Lumia 950 xl, with windows 10 installed, anniversary version. I had the same problem, and my solution was to turn on 'Device discovery' and 'Device Portal', and also keep the 'Developer mode' on.
I believe the only necessary option was the 'Device discovery' though!
Just in case someone still runs into this issue, I had something very similar with my Visual Studio 2015 professional update 1 but I couldn't even deploy to an emulator.
The issue has gone after I upgraded to Visual Studio 2013 update 3.
I had the same issues on Windows 10 with Visual Studio 2015. I updated the the UWP SDK to Anniversary Edition Build 14393, set the target framework to this and it worked. I guess the incompatibility between the device version and sdk version was not allowing the device to be discovered by Visual Studio.
I am developing an application for Windows Phone in Visual studio 2010 ultimate using wp7.1 SDK in Windows 7 32 bit and 3GB RAM. My system often gets stuck and then restarts sometimes when I run the application on wp7 Emulator (2 or 3 times an hour). Before restart it displays the message: "Display driver stopped responding and recovered" and leads to a blue screen displaying "some lines with Contact system admin".
I am not sure why, will need more details. Try installing the 7.1.1 update for the SDK, it is meant for low profile devices, but I am just hoping this will resolve your issues too.

Had the same problem. Just start your sdk installer. There will be a option of repair of deleat. I repaired my sdk first but it still did not work. I then deleted my sdk and reinstalled it. Worked like a charm.
But you must you know that I was not able to delete my sdk too. My antivirus was doing something wrong and stopping the uninstall of my sdk. So I had to delete my antivirus... than my sdk. Than reinstall the sdk, reinstall the antivirus.
It all worked great after.
I have a VB6 app that loads initially (for a small prompt to enter a license key, only on the first time). It works fine on my machine (windows 7).
I had complaints of it crashing on someone else's machine (both xp and 7), so I made a Windows XP virtual machine. I installed it on the virtual machine, it crashed. I wanted to see where it crashed so I installed Visual Studio on the virtual machine so that I would get a debug prompt. When I ran the program again, it worked.
I am more familiar with C++ and had these kinds of problems, so I figured it was some sort of runtime issue.
I found this VB6 SP6 Redistributable Runtime:
http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=24417
I installed that, and it still wouldn't run.
Any ideas where to go from here?
Edit:
I have tried depends.exe, it only shows MSJava, which I've heard I can ignore. Does depends.exe also show things like .ocx (Active X controllers?) that are required?
Also, from the cmd prompt, %errorlevel% doesn't seem to get populated. Is that a VB6 things, or does that indicate that this is truely a crash and not a user exit?
Open the Visual Basic project and check both "References" and "Components" under the "Project" menu.
Since it is crashing with the VB runtime installed it is likely a component that you have referenced in the project that either does not exist (or is not registered) on the client under test.
This should be a simple fix.
I had the same problem on my windows 7 computer.
I have uninstalled everything, changed my windows theme to Windows Classic.
I changed following properties of VB setup file.
Right click on setup.exe and go to properties and in compatibility tab change the compatibility mode to windows XP SP2. And in settings uncheck the following check boxes.
Disable Visual themes
Disable Desktop composition
Disable display scaling on high DPI settings.
Run this program as an administrator
And have completed installation.
Followed by installing VB 6 service pack 6 from here.

Hope it helps.
It may require something else other than just the runtime, have you tried viewing it with dependency walker http://www.dependencywalker.com/ on the machine that it crashes on?
It should quickly point out any missing references.
Maybe try again, create a new VM, but install the remote debugger instead of the full VS.
You should create an installer for your application. There may be more dependencies than just the VB6 runtime. A good installation tool will detect at least some of necessary dependencies for you. Have a look at this question or this question
I've been working with the Windows Phone SDK 7.0 for a long time on my computer. Now I installed the SDK 7.1 (RC) and for some reason I can't start the emulator. I'm getting this error:
Error: The saved-state file C:\ProgramData\Microsoft\XDE{4321-43-432-432-432343234}.dess is corrupt. Please delete the corrupted saved state file and then retry.
I tried suggestions from this article. But they didn't help. Also I tried reinstalling Windows Phone SDK.
Any thoughts how to fix it?
What I'd try:
Open a Windows Explorer window with the file shown.
Delete the file.
Launch the emulator.
Wait for the error message. If there is no error message and the emulator is working, congratulations!
Refresh the Windows Explorer window.
Is the appropriate .dess file restored into the folder? If so, then the file that is restoring the .dess file is corrupt. Reinstall the SDK until it works.
If this doesn't work, do this:
Figure out how your computer is different from the average developer's computer. Did you install some funky customization software? Did you mess up your registry?
Eliminate the differences that you can eliminate - e.g. undo any changes to the WP7 related area of your registry, find and eliminate any viruses {duh!}, kill any nonnecessary background apps like volume managers or printer software, and redownload the installer for the SDK {sometimes the installers are corrupt.}
Install it as a different user. This is the simple equivalent of some of the above steps.
Remember:
The SDK is still RC, so there may be some bugs.
After installing the SDK for the 500th time, it may be time to try something different.
Always install the x64 version on an x64 PC and the x86 version on an x86 PC.
I recently had to reinstall the OS on my dev box and I am now in the process of reinstalling various applications. I had previously installed the WP7 SDK without any problems but unfortunately I'm having problems this time around. The only project type I have available in the Silverlight for Windows Phone category is one that I downloaded from the online templates section.
When I try to open it or any of the WP7 projects I created previously I get a "The project type is not supported by this installation." error. I am not sure what I am missing. I have followed the three steps listed here so I've installed the SDK, the Dev Tools and the Dev Tools fix. The installation of VS2010 itself seems to be fine as I can create ASP.NET and Silverlight applications and run them without any problems.
Has anyone encountered something like this before?
Edit: I have installed Service Pack 1 for VS 2010 but that hasn't helped unfortunately.
Edit: I have also re-installed the Windows Phone Dev Tools and that installation reported no errors but I still get no projects under the Silverlight for Windows Phone category.
Try opening a visual studio command prompt and typing:
devenv /ResetSkipPkgs
I have thankfully resolved this. Last night I uninstalled everything and reinstalled again but this time I made sure to right-click on each executable and select "Run as administrator". That seems to have done the trick as my existing WP7 projects are compiling and running successfully and I can create new ones too. I did run into two error messages however -
"Zune software is not launched. Retry after making sure that Zune software is launched". I got around this initially by setting the target to Windows Phone 7 Emulator instead of Windows Phone 7 Device in the target dropdown on the main toolbar.
"Error: Connection failed because of invalid command-line arguments." I got around this by rebooting as mentioned here.
