Error 2 (GenerateResource)

Question

Hello. What is this error (Windows Phone 8.1 app)? Help me, please.

Error 2 The "GenerateResource" task failed unexpectedly.
System.IO.FileLoadException: Could not load file or assembly 'file:///C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\Microsoft.Build.Tasks.v12.0\v4.0_12.0.0.0__b03f5f7f11d50a3a\Microsoft.Build.Tasks.v12.0.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

Answer 1

Did you add a reference to a dll in a network location?  If you did I would copy the file to your hard drive and add a reference to the local dll.

Answer 2

I have the same problem with the same dll, as you can see the dll is located in gac and it's a default .net library.

Someone can help me?

Answer 3

I got the same problem here. I even did not make any change in the project. And now I can only rebuild my project if remove all the references.

Answer 4

Finally I solved my problem. I used Pivot control in my Windows Phone 8.1 project and when I added any external reference, I got this error. After I changed the Pivot to Hub control, the error was gone. :)

Answer 5

Same problem here, it's probably related to Windows 10 Technical Preview, I have not seen any such problems on Windows 8.1.

So have you found any working solution?
