zerosharp VS Roslyn

Not sure why you would want to use C# without it’s open source framework but here it is: https://github.com/MichalStrehovsky/zerosharp

C# without .NET is like C without glibc. Possible but you'll need another core library. For C# that would be something like Mono or ZeroSharp.

NativeAOT definetely can do bare metal, here's an example of a very basic EFI boot application:

Here's one example repo that uses that feature if you are interested: https://github.com/MichalStrehovsky/zerosharp

This is false. You can even make UEFI application in C#

check https://github.com/MichalStrehovsky/zerosharp/tree/master/efi-no-runtime

Kind of. There's https://github.com/MichalStrehovsky/zerosharp demonstrating some bare metal capabilities.

My understanding is that the .NET team is working toward this with Interceptors: https://github.com/dotnet/roslyn/blob/main/docs/features/int...

.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.
