Microsoft is starting to port VS studio (IntelliSense) which is proprietary to VS code which is opensource. Current C# plugin (Omnisharp) is opensource, so they announce that it will be replaced by a closed source selector that let you choose the opensource or the proprietary plugin with the proprietary as default. It's Embrace, Extend, Extinguish just in front of our eyes, so opensource people are pissed.

Worth pointing out that VS Code is not really open source. The builds are proprietary. It’s based on an open source core but the builds can include anything that Microsoft thinks will be commercially useful to it.

  There is a libre version of VS Code but it is missing features like access to the official extension marketplace. https://github.com/VSCodium/vscodium https://github.com/VSCodium/vscodium

    And all of Microsoft's proprietary extensions look for official proprietary VS Code and refuse to run on open-source builds lacking Microsoft's private key.

    It works reasonably well though, most extensions are in the libre open-vsx.org gallery. Only problem for me is the missing .NET debugger...

Ah come on! It's more complicated than that. Most of the heavy lifting in OmniSharp is done by Roslyn [0]. Roslyn is the open source C# compiler and code analysis library maintained by MS. You cannot overstate how much effort has gone into Roslyn, and how much money MS has invested to make it work. OmniSharp is essentially a wrapper[1] around Roslyn (before Roslyn it was Mono), and while the OmniSharp team did a nice job developing a nice intellisense UX around it all, it is not like MS is taking it all away from them. Incidentally, it is almost certain that new intellisense plugin by MS will also be built on top of Roslyn.

I'm still confused too. How exactly does this "LSP Tools Host" fit into the larger platform of tools? For example, how does it affect me as an Emacs user?
