Bundle the compiler and tools in a Nuget

[granicz]

As it recently came up, it would be often useful in various automation scenarios (Azure deployments, etc.) to fetch and use the compiler tools (fsc.exe and fsi.exe) without requiring a previous F# installation on the executing machine.

I think it's mostly a matter of someone submitting a PR with a nuget package spec like these ones for the FSharp.Core package, and then the package getting pushed. I don't know of any real technical reason why the contents of this repo shouldn't be available in this way, given that they are already part of Linux packages, Xamarin etc.

I look at this, but the FSharp.Core packages only redistribute the already signed and commited dlls.

They also do MonoAndroid, MonoTouch, Xamarin iOS https://github.com/fsharp/fsharp/blob/master/FSharp.Core.Nuget/FSharp.Core.3.1.nuspec#L64
