Generics with interfaces in F #

Question

In C #, you can specify that a generic parameter should implement a specific interface as follows:

public class Something<T> where T : IComparable { ... } 

How to specify this in F #?

Answer 1

General restrictions use the "when" in F #:

 type Foo<'a when 'a :> IComparable> = member x.Bla = 0
