F# is related to the design of Generics for .NET and thus owes a lot to Andrew Kennedy, who co-designed generics with Don Syme.

Although F# is a complete re-implementation of an OCaml-like language, a special thanks go to the OCaml team, in particular Xavier Leroy, who agreed that a 'Caml.NET' was a good thing to do suggested I experiment with language design instead of just implementing OCaml exactly, and to Jacques Garrigue who gave some helpful positive feedback. The OCaml team's work on both the language and the core foundations of programming remains an ongoing inspiration and we look forward to a continued productive relationship.
