What's the easiest way to implement windows resizing that maintains aspect ratio in WPF?


I've got a WPF application which displays a bitmap in an Image control.

I would like to be able to resize the window (and the contained image), but I'd like to maintain the aspect ratio.
Ideally, I'd like to limit the main WPF window to being resized by dragging on the window corners (not the edges).

Are there "thumb controls?"
How would I accomplish this?

Try this

When sizing starts, the dimension that will be artificially adjusted to keep the aspect ratio is determined by locating the mouse position relative to the window. The only remaining imperfections I found are that the position of the window may change when resizing from the corners (except bottom right).
