It is probably a trivial question. But how can I link the F# source code to the Visual Studio so that "Go to definition" would work for F# functions (such as Seq.iter etc.)?
One option would be to grab the F# source, build Fsharp.Core.dll, and then link against the version of Fsharp.Core.dll that you just built. This would give you the ability to debug into F# library source code just like any other library assembly for which you have home-built source code.
