Why is Visual Studio 2017 so slow ????

VS2017 takes excruciating long to to come up with intellisense suggestions, sometimes it even freezes when I'm just typing. This painful experience has largely been made with version 15.6.6.

Consider looking into alternative IDEs:

  • Jetbrains Rider for .net framework and non-media solutions (they don't yet support .net core for F#, there are also problems with the diffGenerator)
  • VS Code for .net core or standard solutions, tooling is provided by the ionide-fsharp extension

According to https://blogs.msdn.microsoft.com/dotnet/2018/04/18/visual-studio-2017-15-7-preview-4/ the new 15.7 Preview 4 should be faster. I'll try it and see if that's true...

Visual Studio 2019 is faster - they also seemed to have fixed the intellisense memory leak.
