I solved the problem as follows, though I haven't understood why, in this case, automatic conversion of function to delegates did not work.
1 2 3 4 5 6
type my_delegate_void = delegate of unit -> unit
let print_to_log_dispatcher str =
let my_delegate () =
g_txt_log.Text <- (DateTime.Now.ToLongTimeString ()) ^ ": " ^ str ^ Environment.NewLine ^ g_txt_log.Text
g_txt_log.Dispatcher.BeginInvoke(System.Windows.Threading.DispatcherPriority.Normal, new my_delegate_void ( my_delegate)) |> ignoreTopic tags

Hi,
I can't understand why the following does not compile:
let print_to_log str (disp: System.Windows.Threading.Dispatcher) = let my_delegate () = g_txt_log.Text <- (DateTime.Now.ToLongTimeString ()) ^ ": " ^ str ^ Environment.NewLine ^ g_txt_log.Text disp.BeginInvoke(System.Windows.Threading.DispatcherPriority.Normal, my_delegate) |> ignore__
It seems the compiler can't convert my_delegate to System.Delegate. What am I missing? Thank you.
