Question

Assume i have control button with name “button1” and function with name “doSomething”. Function “doSomething” is called from another thread.

i have two method to call function doSomething from UI thread.

First, from control button dispatcher

this.button1.Dispatcher.BeginInvoke(new Action(() => { doSomething(); }));

and Second, from application dispatcher

this.Dispatcher.BeginInvoke(new Action(() => { doSomething(); }));

The result is same, what is the real different ?

Answer 1

The same dispatcher instance is referenced in all controls owned by the same thread. There is no difference.
