OK, I'm sure this is an easy thing .. I haven't used this program in a long time. I downloaded the latest (.NET 4.0) version of Reflector, but I don't find the System.Web.Mvc assembly in there.
You can use File/Open to navigate to an assembly, but if the assembly is in the GAC then the easiest thing to do is File/Open Cache and then use the filter to find system.web.mvc and then double click it to load it.
Is there a way to get it there?? Thanks.
