C# is a versatile, object-oriented language with a rich ecosystem, making it suitable for a wide range of applications, especially in enterprise environments. Haskell, on the other hand, is a purely functional language known for its strong type system and concurrency support, making it ideal for tasks that require high reliability and mathematical correctness.
