Hi John,
Sorry for the late reply.
I worked on a C# (MSIL) importer a few years back while I was working in Inria.
This parser was based on Mono project and a library Mono.Cecil that provides API to access MSIL.
The importer I wrote was able to extract the basic information required to create FAMIX model (Classes, Namespaces, methods, attributes, invocations, accesses, params).
I think it might also have started to extract Generics but that part might not be complete. I didn't rewrite FAME/FAMIX for C# but used a library to transform FAME/FAMIX in Java to C#.
That meant that I could reuse the meta-model + MSE import/export from existing code.
But I haven't been able to work on it since 6 years now. But if you are interested, you may have a look here at the code here:
One day when I get some time I would like to replace Mono.Cecil with Microsoft's parser that has been opensourced since.
HTH,
regards.
