The things you cite as missing in C# can be found in F# on .NET Core. Have you ever tried it? I find it hard to stomach C# after delving deeply into F#, and you still get to use Dapper! Swagger though... not sure if anyone ever got that working well with Giraffe or any other more functional web framework. When I say "working" I mean automatically generating the Swagger docs for you.
