When playing with minimum form size, I noticed, that minimum form size is restricted to system minimum form size in Form.SetBoundsCore(...). When I look into IL disassemly, I found, that this .Net method always corrects what you give it (width and height) to SystemInformation.MinimumWindowSize if they are smaller and the form don't have a parent and its FormBorderStyle is FixedSingle, Fixed3D, FixedDialog or Sizable.

The easiest solution to this problem is not handling WM_WINDOWPOSCHANGING, but simply setting FormBorderStyle = System.Windows.Forms.FormBorderStyle.None in the form constructor.
