MVC 3 references automatically updates to MVC 4

Question

I just installed the Visual Studio 11 and MVC 4 beta on my local machine. However, whenever I open up an MVC 3 project (that I want to keep as MVC 3), all the references have been updated to the version 4 DLLs. Surely it shouldn't be doing that?

The MVC 3 project opens in Visual Studio 2010.

UPDATE:

I looked in the .csproj file of my MVC 3 project and I can see all of the references in place, but they don't specify paths. If no path is specified, does it just pick up the latest version of the DLL?

Answer 1

You can specify which version of an assembly you require in the Include attribute as shown here:

<Reference Include="System.Web.Mvc, Version=3.0.0.0" />

Without specifying a path or version, Visual Studio will match on any assembly with the same name.
