How to round the edges of a program window in C#?

Question

WPF

How to round the edges of this panel or how to apply no styles at all?

Answer 1

To style the frame, you need to remove the one provided by the operating system in the window style and write your own with the desired functionality. For rounding, for example, a background image with transparency is used (in this case, this transparency must also be enabled for the window).
