Visual Studio 2008 Explicit Reference Error

I have a project which references a dll in the same solution (called "Common"). Common has two types of errors with the same names but different namespaces i.e.

Common.Login.UserDeleted Common.Imaging.UserDeleted

When I type UserDeleted visual studio recognizes both of these and asks for which it is ("ambiguous reference"). I right-click UserDeleted and select one of the two above, yet it then says that the type or reference doesn'开发者_JS百科t exist! It doesn't make any sense. Why is this happening? I can't compile my program until I find a solution to this, thanks

Sorry to bother, the problem was that in my Common dll there was one type that had the same namespace as my client dll (i.e. Client.Common instead of Common). I don't know why it confused Visual Studio but it compiles now. Thanks again for offering your assistance
