> marketing F# as a C# replacement I agree with this; it should of never be marketed this way. For me C#, once you get past a lot of the initial ceremony of the language and all the libraries/OO patterns you need to learn (DI, mocking frameworks, etc) the gap between C# and F# gets a lot smaller. C# isn't a bad language and has a lot of features, it just also has a lot of history that adds complexity. IMO the benefit of F# and other newer languages is about simplifying things while keeping the same level or more expressive power. If you've already learnt all the patterns and frameworks in C#, have reasoned around the historical complexity and the ways around things seem second nature to you there isn't much to gain and some things to lose (e.g. familiarity, politics, fear of change, support). Grab a Go, Python, JS dev however and show them idiomatic F# code vs idiomatic C# code (with tests, and scaffolding) and from first hand experience I've seen what they choose. Even more so because typically these people typically use tools like VS Code and not a full blown IDE, where F# has the advantage at present.
