Vista - Tool To Create Function Map Of C#.NET Project In Visual Studio 200

I've been assigned to an existing project to assist with some customization
requirements, but most of the documententation is in Japanese and very
lacking in useful pictures or diagrams.

What I'd like to do is create a function map which includes a list of which
assemblies/members contain a call to another assembly/member, or reference,
or method, or whatever-they-are-called.

That way, if I see something like SecurityManager.ChangeBilingalMode (sic),
I have some clue as to where that call originated.

Is there something included with VS2005 that does this, or maybe one of the
Office 2007 products?
