It's funny. Nobody complains that there is a lack of free multi-platform desktop GUI profiling tools for Go, Python, Ruby, Elixir etc. Somehow we just accept those languages are only for web services, web apps, and command-line utilities.
What is the problem with Microsoft keeping "nice to have" desktop GUI stuff for their own proprietary ecosystem when everything else has open sourced? Including the primitives needed for the community to build their own GUI and developer tooling stuff, just like JetBrains did with Rider.
