WinUi3 显示另一个窗口

Question

If you use another Window on WinUi3, you will get an Error. Do you know how now?

Answer 1

Creating new windows is currently not supported in the stable release (version 0.8.2) of WinUI3.

If you install the latest release of the experimental channel (version 1.0.0-experimental1), you can however create and display new windows like this:

var win = new Window();
win.Activate();
