You missed two that I can think of: (1) the runtime written in F# that Frank Krueger’s Continuous uses (and I believe also Xamarin Live player uses in some fashion.) (2) Goa WinForms was a C# compiler that targeted the Adobe Flash Player, and implemented part of the BCL and WinForms UI. If you include the CrossNet I think this also counts.

Nice! Thanks for the info, I'll check those out, I'd not heard of either of them.

I think that an update to the post is due, turns out that I missed quite a few!
