Could not load file or assembly 'DotNetOpenAuth.Core

Question

I get the following error when I start my asp net mvc 4 application:

Could not load file or assembly \'DotNetOpenAuth.Core, Version=4.0.0.0, 
Culture=neutral         


        

Answer 1

I had similar problem. It was really strange as the project was running OK a day before.

Removing obj and bin folders from the project folder, cleaning the solution and rebuilding it worked.

Hope that helps.
