I've had this problem before, but then all i needed to do was to clean and rebuild the project. Now that doesnt seem to work anymore. When i start my Asp.Net MVC3 project debugger, the site is opened in my browser. Instead of getting the first page presented in the browser, i get this error
Parser Error Message: Could not load file or assembly 'System.Web.WebPages, Version=220.127.116.11, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

I had this problem. Maybe it occurred when I installed .NET MVC v4 over the top of MVC v3, not sure.
Anyway I removed the
System.Web.WebPages reference from my project. Then in the Add Reference dialogue .NET tab there were two System.Web.WebPages references listed, a version 188.8.131.52 and a 184.108.40.206. I made sure to add the version 220.127.116.11 one as that was the one that was missing.
