Is there any opensource meta-circular CLR implementation?

Question

Is there any open source meta-circular implementation of .Net CLR? I know MONO is not entirely written in C# so I was looking for some sort of open source project which implements .Net CLR entirely in C# (something like Maxine for JVM) to get better understanding of .Net CLR.

Have you read about Shared Source CLI, code-named "Rotor"?

Some links:

Also it is interesting the Roslyn project, which is a C# compiler written in C#:
