Buildalyzer VS Roslyn

https://github.com/daveaglick/Buildalyzer <-- Love this library.

So I am working with Buildalzer package (Pretty cool, worth a peek, its not mine) which helps examine code in projects, and MSBuild type things.

Agreed, Roslyn Workspaces can be helpful. I use them for some code-gen of TypeScript types based on my C# model. There's also Buildalyzer which can help simplify working with Workspaces.

.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.
