F#: Using INotifyPropertyChanged for data binding

Question

How would one implement INotifyPropertyChanged for use in an F# type? Thanks!

Answer 1

It's basically the same as in any other language:

open System.ComponentModel
type MyType() =
  let ev = new Event<_,_>()
  let mutable str = ""
  member x.StringProp
    with get() = str
     and set(str') =
       str <- str'
       ev.Trigger(x, PropertyChangedEventArgs("StringProp"))
  interface INotifyPropertyChanged with
    [<CLIEvent>]
    member x.PropertyChanged = ev.Publish
