Dispatcher.CurrentDispatcher.BeginInvoke Not Invoking

Question

I have a FileSystemWatcher and the events raised by this when a watched file changes are raised on a different thread from the UI thread. To avoid and cross-thread acess volation fun, I am attempting to use

public void RaisePathChanged(object sender, RenamedEventArgs e)
{
    Dispatcher.CurrentDispatcher.BeginInvoke(new Action(() => 
    {
        // Some code to handle the file state change here.
    }));
}

This compiles fine and the RaisePathChanged is fired as it should be. However, the code inside the delegate Action(() => { /*Here*/ }) never gets called/invoked, the code is merely skipped.

Why is the code being skipped, how can I fix it and is this the best way to insure code is run on the thread that created it in WPF?

Thanks for your time.

Answer 1

You are mixing up things.

Dispatcher.CurrentDispatcher is not the same as Application.Current.Dispatcher.

The second one is the one you seem to be looking for.

Take a look at this.

Dispatcher.CurrentDispatcher vs. Application.Current.Dispatcher

Try it out with application dispatcher.
