The following projects:
Are based on the .net ecosystem. Nitra is a language workbench which in the future can support C#, F#, VB syntax with while being extensible also.
I am very interested in these projects propering through I am not part of the team. Wondering if there is anybody here who might like to contribute, support and / or sponsor in seeing this through. Also wondering if MS and / or DNF can do something in furthering the development of language workbenches.
