I have just released the pre-release version of a pet project- a template for writing Omniverse extensions in F#.
It uses the Fable transpiler to cross compile the F# to Python. You don’t have to do anything other than install dotnet (if you have not already done so) and do a repo build. All the Fable magic is in the modified extension premake5 file.
Right now to call kit functions you have to use the Fable emit facility and write the calls in Python, but a Fable binding to kit is my next project.
