Hi,

I am using MS VS 2019 v16.9.5, C#/WPF and I can not understand to window size. See the picture below. Height of whole window is 400pixels - the label 400 is on the right side of the window. Inside the client area of my window is a grid with 2 rows with heights 100 and 300 pixels. This is clearly visible on the left side of my image below. My window has a title bar with height 22 pixels. The biggest problem is that I can not understand how 100 + 300 + 22 = 400. Is there someone responsible who can explain me it ?

    I am sorry but according to mechanical engineering drawing standards/rules the WPF visual designer shows wrong sizes. MS should correct/repair this terrible mistake.

    Look at your Window element; the element first in the XAML. It has Height="400".
