.NET 4.0 / MVC 3 - Where is System.Web.Mvc?

I've down开发者_运维知识库loaded the latest Who can help me? s#arp arcitecture app from codeplex. This is a VS 2008 / MVC 2 solution, and I have VS 2010 / MVC 3 - no probs I thought, I will convert it.

However, my web projects are complaining about a missing assembly System.Web.Mvc, which does not seem to exist anywhere on my system. I haven't been able to find anything to the contrary that this assembly has been superseded.

Any ideas?

Have you installed ASP.NET MVC3 ?

When you install visual studio 2010, it's shipped with MVC2, so you still need to install MVC3.

After installing MVC3 you should have System.Web.Mvc into your GAC.

Hope it helps
