Change boundaries of the desktop with program.

I am using Window 10 with C# and WinForms (but I am open to using WPF or UWF if needed).

 

What I would like to do is to create a banner app form at the top of the screen. I need it to act similar to the task bar, with respect to acting as a boundary for the desktop. In other words, when someone maximizes another program window, it should stop at the bottom of my banner, just like it stops at the top of the taskbar. I don't mind if someone want to drag a window underneath it (just like with the taskbar), but I don't want people getting frustrated when maximizing a window and part of it being blocked by my app. 

 

Thank you for your consideration.
