The “GenerateResource” task failed unexpectedly. System.InvalidOperationException

(According to the error messages, they are all common errors. I could not give the most direct correct answer for this issue, I can only give you some troubleshootings. In order to avoid losing contact in the round-trip comments, I post those troubleshootings as answer instead of comments.)

To resolve this issue, please try following methods:

Add <NetFx40_LegacySecurityPolicy enabled="true"/> into the VS2012 DevEnv configuration file, you'll find it in C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe.config

Adding the following under the first property group in the Project file:

<PropertyGroup>
    <GenerateResourceNeverLockTypeAssemblies>true</GenerateResourceNeverLockTypeAssemblies>
</ProjectGroup>

If you have app.config file in your project, please try to add following into it:

<runtime>
  <NetFx40_LegacySecurityPolicy enabled="true"/>
  <legacyCasPolicy enabled="true"/>
</runtime>

If above not helps you, please try to reinstall the Visual Studio 2012.

Hope this helps.
