omnisharp-vscode VS Roslyn

They announced a year ago they are working on better C# support in VSCode https://github.com/omnisharp/omnisharp-vscode/issues/5276

OmniSharp (soporte de C# en VS Code): Licencia MIT

Let me try to find that post. It's basically the drama around this

> They did a wonderful job with C# and .NET Core.

And VSCode. One thing all three have in common is that they are all FREE to use--they don't make Microsoft any money directly.

And, for the segment of the developer tools market that wrangles C# code, if VSCode gets too good, it becomes a threat to a cash cow: Visual Studio.

Open source. OP is referencing a decision Microsoft made last year to include some closed-source components, in particular the debugger from Visual Studio, in the default C# extension for Visual Studio Code. There is a Samsung-provided open source debugger available if you absolutely require it, but the closed source stuff doesn't have any usage restrictions afaik.

.NET is a little smarter about switch code generation these days: https://github.com/dotnet/roslyn/pull/66081

Recently, while creating some experimental C# source code generators (xafero/csharp-generators), I was just concatenating strings together. Like you do, you know, if things have to go very quickly. If you have a simple use case, use a formatted multi-line string or some template library like scriban. But I searched for a way to generate more and more complicated logic easily - like for example, adding raw SQL handler methods to my pre-generated DBSet-like classes for my ADO.NET experiment. You could now say: Use Roslyn and that's really fine if you look everything up in a website like SharpLab, which shows immediately the syntax tree of our C# code.

At runtime, the Case C# expressions are embedded into a function and dynamically compiled into an assembly using the Roslyn C# compiler. Then the function that contains the expression is called (e.g. CaseAvailableFunction.Availablle()). At runtime, the function provides various methods to access stored case values as well as the current input data.
