Question: How to Maximize, Minimize, Restore WinUI window from code?

See original GitHub issue

Is there an API that manipulates a WinUI window size/state from code?

I have used the TitleBar API’s that I am aware of to set a custom TitleBar

            ExtendsContentIntoTitleBar = true;
            SetTitleBar(myControl);

While this works to set the TitleBar, the Minimize/Maximize/Close buttons are now unresponsive. I would like to overlay my own buttons to restore the broken behavior. Or, if there is a better example for how to set the custom TitleBar that does not disable the main window buttons, that would be a great solution as well. I posted this on StackOverflow, but have not had any responses.

This is for WinUI 3 (Project Reunion 0.5), Win32 Desktop

@omnilogix The custom Title bar has a couple of bugs that depending on the XAML layout caption buttons aren’t rendered on the top of the visual tree. We have bug fixes ready for 0.8 GA.
About Maximize, Minimize, and Restore WinUI window from code, you can find some samples at DesktopWindow that shows you how you can achieve it using Win32 APIs. These window functionalities will be added post v1, per the current engineering plan.
