Mono and unity version?

Hello, i might like to develop an extension in f# that is using some external dlls.

Afaik recent unity versions (5.5) use a pretty up to date mono compiler (4.4).

Oxide still targets .net 3.5 and i dont know what U3D version Rust uses.

Can somebody enlighten me on the current situation and implications.

Thx a lot.

 

Ah, i guess i was wrong.
"Scripting: Upgraded C# compiler to Mono 4.4. The new compiler still targets C# 4 and .NET 3.5, but provides better performance and many bug fixes."
Unity - Unity 5.5

Might change soon?
