So WPF windows only have four resize mode options: NoResize, CanMinimize, CanResize and CanResizeWithGrip. Unfortunately, the
NoResize
CanMinimize
CanResize
CanResizeWithGrip
If you set
WindowStyle="ToolWindow"
In your window's properties, it will give you a resizable window with no minimize or maximize buttons at the top. It'll be square looking and the close button is also square, but at least minimize and maximize aren't there!
