Of all the possible ways to handle toolchains on Linux, I'm quite happy with asdf[1]. I've successfully built stand-alone fsharp/csharp "Hello worlds" off of dotnet via asdf - but I've not used dot.net in anger.

I chiefly like asdf because I typically need at least two toolchains (with various versions for various projects) - eg ruby and nodejs, or python and nodejs.
