ClearScript VS Roslyn

Microsoft makes ClearScript

I've used ClearScript before to use JavaScript as a DSL in a tool. No issues at all. https://github.com/microsoft/ClearScript

I've had good luck with Microsoft's Clearscript - https://github.com/microsoft/ClearScript)

The ClearScript library https://github.com/microsoft/ClearScript enables V8, JScript and VBScript to be used as extension languages for .NET languages. Our company uses it extensively and has done so with great success for years. Anything done in C# can be exposed to the scripting language and to some extent back the other way as well.

Along the same lines, I use Microsoft ClearScript which uses JavaScript.

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.
