How to open a window in a separate thread?

Question

I\'d like to do:

Window newWindow = new Window();
newWindow.Show();

while (true) 
{
    Console.Write(\"spin\");
}

I.e., I\'m doing an int

You shouldn't try to open a new Window in it's own thread.

Instead, push the computational work you're doing into a background thread, and leave the UI thread free. The simplest option for this is typically to use BackgroundWorker. It handles the marshaling of progress and completion back to the UI thread for you automatically.

However, you can do this yourself using threads or Task/Task, as well. Just remember to use the Dispatcher or a TaskScheduler created from the UI context for anything that will update the UI, such as progress notifcication.
