F# and generic types

Question

Its possible to create this in f#?

public TTarget Map<TTarget>(string SQL) where TTarget : new()
{
}

Answer 1

let map<'T when 'T: (new: unit -> 'T)> (sql: string) =
    new 'T()

Answer 2

Actually, the constraint is unnecessary. This works just as well.

let map (sql: string) = new 'T()
