Remarks
When you add a DesktopWindowXamlSource to your desktop application, by default the DesktopWindowXamlSource does not automatically handle focus navigation via keyboard events such as the Tab or arrow keys. Call the NavigateFocus(Microsoft.UI.Xaml.Hosting.XamlSourceFocusNavigationRequest) method to programmatically give focus when the user navigates to the DesktopWindowXamlSource.
Handle GotFocus event to be notified when user enters the DesktopWindowXamlSource via some non-keyboard event, such as a mouse click, and you want to keep the state of the UI in the host desktop application up to date.
