Worse is better: C# versus F#

In this article, Mark Seemann contends that F# is a better programming language than C#, despite C# being more popular. He notes that both run on .NET, simplifying comparison. He argues F# has feature parity with C# and goes beyond, offering advantages in expressiveness, type safety, and functional programming paradigms. The article is part of a series exploring why superior technologies sometimes lose popularity, using examples like VHS vs Betamax. It targets developers interested in language comparison and functional programming on .NET.
