From the post: Specifically, the following are in RC: - FSharp.Core as a .NET Standard NuGet package - The F# compiler running on .NET Core as a .NET Core console application - F# support in the .NET CLI and the .NET Core SDK However, the following are not supported at this time, but will be supported in a future Visual Studio 2017 update: - F# support for .NET Core Visual Studio tooling - F# Interactive (FSI) running on .NET Core as a .NET Core console application
