How do I implement a chromeless window with WPF?

Question

I want to show a chromeless modal window with a close button in the upper right corner. Is this possible?

Answer 1

You'll pretty much have to roll your own Close button, but you can hide the window chrome completely using the WindowStyle attribute, like this:

That will still have a resize border. If you want to make the window non-resizable then add ResizeMode="NoResize" to the declaration.
