Hi,
I wanted to check lifecycle of the WinUI3 window, when it will be cleared from the memory and who will be responsible for clearing all the content of the window and the window itself. What will happen when the window close is triggered and who is responsible for clearing all the contents of the window in WinUI3 desktop app.
I tried checking online for the official documentation on windows lifecycle, but was not able to find it.
It would be of great help if you could point me to the right documentation
Thank you
Hello,
Welcome to Microsoft Q&A!
A Window is created by new or equivalents and is closed by Window.Close Method or Application.Exit Method.
An instance of the object that is specified by the root element of the XAML file is maintained by WindowsAppSDK and you must free your resources.
Thank you.

Thank you for your response.
We are building the application programmatically in c++, we are not using new or make. and we are not calling IntializeComponent().
Window window; // this will be a class member of custom window class
window.content(panel); // Add data
window.Activate(); // Acticvate
In this case, who will be responsible for clearing all the widgets and window from the memory when close is pressed.
When close is pressed, WindowsAppSDK should clear all the widgets and window. For example, see startupWindow. You can also debug to double check.
