Stymied by ASP.NET Compilation Error CS0009

Question

I'm getting error below when I debug my ASP.NET MVC app.

Any thoughts on how I could solve this?

Any idea how the problem would have occurred in the first place? I promise you I didn't go randomly deleting dll's from deep within protected directories on my system.

Server Error in '/' Application.
