I think due to Visual Studio's caching, some of the dll's aren't compiled properly and this situation can happen. If you do, delete all temp files from following locations:

• C:\Temp
• C:\Users\%Username%\AppData\Local\Microsoft\VisualStudio
• C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files
• C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files

• AppData\Local\Temp\Temporary ASP.NET Files

Then restart the Visual Studio. This is how i resolved.
