Here's what I'll say: By sitting the F# language service atop Roslyn Workspaces, F# in Visual Studio is in a far better place infrastructure-wise than it has ever been. Roslyn Workspaces are the lower-level piece that nearly every bit of .NET IDE work is done in. A great example of how that enables F# in other areas is how the idea of support for the Roslyn Project System[0] went from a complete unknown to a reality. The work needed to support F# in various areas went down by orders of magnitude as a result of this work. [0]: https://github.com/dotnet/roslyn-project-system/pull/1670 P.S. I'll be in London for a week. Even if you can't make F# Exchange, I'd love to meet up for coffee, beer, or whatever!
