Making a CLR/.NET Language Debuggable

What are some resources for making a CLR/.NET language debuggable? I'm developing an ActionScript 3 to IL compiler, which uses DLR CallSites and CallSiteBinders to handle the dynamic aspects of the otherwise static programming language. I'm looking for any information on making the emitted IL map back to the source code, and I'd also like to know how I can make the dynamic call sites map back as well.

So this is ultimately two questions:

• How can I make the IL debuggable?
• How can I make the DLR call sites debuggable?

Any help would be greatly appreciated!

What I'm looking for in terms of "debuggabilty"

Within attached Visual Studio instance:

• Step through code
• View locals
• View stack trace
