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

By installing the following two packages I resolved this problem on VS2012 Professional Update 4 RC:

1. Open the Package Manager Console from the Menu:

   Tools| Library Package Manage | Package Manager Console

2. Install-Package DotNetOpenAuth.AspNet

3. Install-Package Microsoft.AspNet.WebHelpers

Hope this helps for you!!!
