Best Answer

I had this problem after installing Visual Studio 2012.

What solved for me was installing the Visual Studio Updates:

  1. Tools> Extensions And Updates
  2. Select "Updates" in the accordion list on the left.
  3. Select "Product Updates".
  4. Update to the newest version (At the time of writing of this answer it was Update 4)
