Worked for me!!

"This will really work like a champ :

Solution: Try to delete ComponentModelCache folder from below location.

C:\Users\v-ramare\AppData\Local\Microsoft\VisualStudio\11.0

And after successful delete recreate the folder with same name "ComponentModelCache".

Thanks
Ram"

I received this problem.

I traced this problem to the following windows update
Security Update for Microsoft.NET framework 4.5 (KB2840642)

I uninstalled this update and the error stopped ocuuring.

I had the same problem, but I had kb2805222 update installed and no kb2805221. Uninstalling this update resolved the problem.

My VS2012 worked well yesterday. But today I open it. This error happens. I can't open C++ project (Windows Phone C++ library, runtime component) and my previoused added C++ project is now "load failed"
