> #1 tooling: visual studio integration of F# is poor. You don't get cross language usage reference, so you lose all the benefits of static typic. Projects and references are a mess. Being primarily a scripting language, it feels like a toy language

Could you clarify what you mean here? Although things like Go to Definition and Find all References don't work across C#/F# boundaries (yet), but you absolutely get IntelliSense and the benefits of static typing. F# isn't a scripting language, although it does support F# scripts.

You get intellisense alright. But using C#, I never need to #open the namespaces myself for it to find the types I am using or the extension methods I need. (Maybe this is because I use resharper, but still, it really slows me down).

Also the benefits of static typing are that it makes it easy to refactor. Here if I change things in C#, I need to grep my F# scripts for usage, it's a real pain.

This is actually added in F# tooling for VS 2017! Both via a lightbulb code fix and with IntelliSense itself. If you have a reference to a .dll with symbols, the IDE can suggest an open statements for you.

And FWIW, I remember complaining about this to Don Syme something like 5+ years ago, and while he gave lip service to the idea that F# needed better tooling (and better tooling interop with C# specifically), I don't think he was really convinced.

It's the "Go to Definition" and "Find all References" pieces that are so annoying to me, and slow me down tremendously. It means that (practically) you have to do your whole solution in one language for it to feel like a unified solution, and that makes it hard to start by bolting an F# project onto an existing solution.
