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

If you don't want use OAuth, remove references: both the WebPages OAuth DLL (I think it's Microsoft.Web.WebPages.OAuth.dll ¹) and DotNetOpenAuth DLLs.

¹: You can find the filename in Calling assembly. So, removing all calling assembly of DotNetOpenAuth.Core should work for you. This approach should work for other unused missing references.
