F# with .NET Core? Yes, it works fine.

There are some challenges coming up with design changes to the compiler and C# that might overlap what F# already has but it'll get sorted out.

.net core F# support has been pretty great from the initial stages of .net core from my basic usage. Biggest challenge seemed to be around type providers (F# system of generating strongly typed classes from dynamic data such as XML, CSVs, HTTP etc) but that's largely resolved. More info at https://github.com/fsprojects/FSharp.TypeProviders.SDK

Great resources for getting started with F# at https://fsharp.org/

My personal preference is generally to install the SDK and use the http://ionide.io/ with VScode as it seems to work most reliably cross platform.

I'd be very much interested how anyone is using F# on Linux without mono.

I have .NET Core but the whole thing seems to require Mono and it isn't clear from fsharp.org that you can do without.

Mono is not required: https://docs.microsoft.com/en-us/dotnet/fsharp/get-started/g...
