在Windows 10中将1px边框颜色更改为自定义颜色而不是强调色

Question

Windows 10 draws this 1px border in the accent color around most windows including the window of our WPF app or as seen here cmd.exe :

But Visual Studio (which is also WPF) has changed that to fit its status bar color:

We would like to do the same, but I found nothing on how we can do this for WPF.
Does anybody know how this can be done?

Answer 1

I believe you would need to add a window proc function to your window and handle the WM_NCPAINT message. This is similar to what's done in this code project article: Class for drawing a flat color border though he's doing it on child controls, the principle is the same for top-level windows.
