I've come upon this situation a few times before. I wish to reference a type in my XML comments, but the type is contained in an assembly not referenced by my project.

In A.Dll (references B.DLL):

using B;
///
Hai I'm SomeClass and I use  to do my work
public class SomeClass {/*...*/}

In B.DLL (does NOT reference A.DLL):

///
 I can't  in this summary 
public class LoserClass {/*...*/}

In the comments for LoserClass I need to reference SomeClass but I can't due to the fact that B.DLL doesn't reference A.DLL (circular reference).

Is there some way to include the assembly information in the cref within LoserClass' code documentation, so that A.SomeClass can be resolved by the XML documentation generator?

(btw, you can't always resolve this by moving classes as it can cause circular dependencies in other places)
