Thanks for link and the information Chris, Goo.NET seems very similar to
what I had in mind, I will look into it.

I was thinking much along the same lines as you were. A C# tool would import
.NET assemblies and generate Managed C++ code that wraps calls to the the
framework with the MzScheme extension DLL protocol. One .NET class would map
to a MzScheme type + a cluster of functions implementing its methods.

I am speculating that it might be possible to map .NET namespaces into
MzScheme modules (a hack no doubt, but maybe one that can be lived with). I
also think that in MzScheme .NET method overloading can be resolved by  the
exported MzScheme functions themselves (MzScheme allows variable arguments
in extension code). I was not planning on doing much to support inheritance
for now - I was sastisfied to have exported functions able to work on .NET

Something like this:

; StreamWriter inherits from abstract class TextWriter which defines

(require (lib "System.Text" "dotnet"))

(define w (make-StreamWriter "out.txt"))

(TextWriter-WriteLine w "Hello {0}" World")

How did you address ref arguments? I have no idea how to represent this in
