Answer 1

Right click on System.Web.Mvc in your reference folder and make sure that copy local is set to true. That should add System.web.mvc to your bin folder and it should correct the problem.

Answer 2

Right Click to Project -> Manage Nuget Packages for solution than update

Microsoft.AspNet.Mvc and Microsoft.Net.Compilers

Answer 3

Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.0,..."

Your application is using MVC3, but according to your own comment, the server has MVC2 (2.0.50217.0).

Answer 4

I had this problem when deploying to a server which ran MVC2, the files which will need to be included in the build are:

Microsoft.Web.Infrastructure.dll
System.Web.Helpers.dll
System.Web.Mvc.dll
System.Web.Razor.dll
System.Web.WebPages.Deployment.dll
System.Web.WebPages.dll
System.Web.WebPages.Razor.dll

Phil Haack has done a good post here (for how to solve if you run into this problem when deploying)

Answer 5

If you have rights to do so, you can download and install MVC3 on your webserver.
