docs VS Roslyn

MS docs ar now on github. Licence lists "CC-BY-4 and MIT licence found" https://github.com/dotnet/docs/tree/main

Yeah, I saw that devdocs and the like don't include what was previously not cross platform and not popular for linux guys: C#, msbuild.

This ability to nest object/collection initializers is not documented TMK and if you feel it is you could update this nearly 4 year old ticket requesting it be documented: https://github.com/dotnet/docs/issues/12979 .

To be like, really pedantic, C#'s foreach will perform an implicit typecast in some scenarios, which can cause the enumeration to throw an InvalidCastException when it hits an item that can't be cast to the specified type (in this case, ShadowCaster2D).

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.

I like to use the roslyn coding practices for C# projects (https://github.com/dotnet/roslyn/blob/main/docs/wiki/Contributing-Code.md)
