Question

Here is the stack trace:

[FileLoadException: Could not load file or assembly 'Microsoft.Web.Infrastructure' or one of its dependencies.

Everything worked fine. I have never changed anything in my links. I have Microsoft.Web.Infrastructure.dll added in my project and Copy local is True.

Everything was fine until I added a new view without the main page. What's happening? How to solve this problem?

Answer 1

I had the same problem, it turned out that Visual Studio blocked the DLL. Restarting Visual Studio fixed the problem, although I still don't know how to do it , why .
