How can I set a minimum size for the window in WinUI 3?

user_8443430 · Answer

Currently, there is no MinSize or MaxSize properties yet on the Window class in WinUI3.

A workaround is that using the SetWindowSubclass function to hook WM_GETMINMAXINFO and set the min size.

Please check this Github link: How to set minimum window size (Desktop) which contains more discussion about this.
