It's also important to add F# is an inspiration for an amazing MS Research effort, F* [1].
Furthermore, it is also worth checking Dafny [2] (Spec#'s successor). The relationship between Dafny and C# is equivalent to the relationship between F* and F#. Both languages try to refine their predecessors semantics and augment them with practical constructs to prove program correctness.
Some of the largest software artifacts ever verified have been implemented in Dafny [3], and F* is also looking quite promising.
