Silverlight OOB - own chrome with Windows 7 docking behaviour

I'm creating Silverlight OOB application with its own chrome (title bar, minimize, maximize buttons and so on). I've implemented the resizing functionality and everything works quite good.

Still I would like to add one more functionality. I would like that my app has good docking behavior in Windows 7 OS - maximizing on docking to the top of the screen, changing size to the half of the screen on docking to right or left.

How can I do this? I will be appreciated for any help.
