WPF Window - Only allow horizontal resize

Question

I want to only allow my WPF window to be resized horizontally. How best can I achieve this?

Answer 1

It's kind of a pain. Basically you need to set up a hook function to process windows messages. Then you would catch the WM_SIZING (0x0214) message and modify the parameters so that the horizontal dimension could not be changed.
