To add to this, there are also official Microsoft extensions to VSCode which add absurdly useful capabilities behind subtle paywalls. For example, the C# extension is actually governed by the Visual Studio license terms and requires a paid VS subscription if your organization does not qualify for Visual Studio Community Edition.

I'm not totally sold on embrace-extemd-extinguish here, but learning about this case was eyebrow raising for me.

C# extension is MIT, even though vsdbg it ships with is closed-source. There's a fork that replaces it with netcoredbg which is open.

C# DevKit is however based on VS license. It builds on top of base C# extension, the core features like debugger, language server, auto-complete and auto-fixers integration, etc. are in the base extension.
