Could not load file or assembly 'Antlr3.Runtime (1)' or one of its dependencies

Try to delete the temporary files for ASP.Net by doing one of these:

• Enter %TEMP% in the File Explorer and delete all the temporary files.
• Go to folder "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files" and delete all files.

I encountered the same problem when experimenting with the free Nlog logging platform.

This helped me:

Enter %TEMP% in the File Explorer and delete all the temporary files.

After that I didn't get the error when starting my MVC5 project in Visual Studio.
