VisualFSharp VS Roslyn

There's docs about how the compiler generally does optimizations here: https://github.com/dotnet/fsharp/blob/main/docs/optimizations.md

You should add your +1 to https://github.com/dotnet/fsharp/issues/8764, which would add a syntax like #r: project ... to FSI.

So when people are mad about MS and F#, one can see here that: https://github.com/dotnet/fsharp/graphs/contributors MS does a lot more for F# then people being all pessimistic in reddit.

F# AOT feature tracking

Can't speak to the others, but I'm pretty sure the F# team just doubled or tripled in size (it's still small though). Also the GitHub repo is very active: https://github.com/dotnet/fsharp .

Have you tried the workaround listed here? https://github.com/dotnet/fsharp/issues/12239

.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.
