System.Timers.Timer invoke WPF component's method

Question

I have a class, that is responsible for the logic of a classic snake game logic, that uses System.Timers.Timer. Because the exact same class is used for a Windows Forms version of the exact same project, I don't want to change that.

How can I connect a WPF window's method to an event that was designed to be used for WinForms (ISynchronizeInvoke)? I'm searching quite a while to achieve this without rewrite my logic class.

It is pretty unclear how you used ISynchronizeInvoke. But you could just write a little helper class that implements it and uses Dispatcher to implement the four methods. It uses the same names, except that InvokeRequired is Dispatcher.CheckAccess(). — Hans Passant

this was a missing link for me but may not be enough. I may need to open another question, or refine this one... — Adam L. S.

You can use the Dispatcher to invoke to the UI thread

private void ThreadingTimerTick(object state)// or whatever your method is.
{
   Dispatcher.Invoke(DispatcherPriority.Background, (Action)delegate()
   {
     // do stuff
   });
}
