Doing it the new way with content before activating the private void CreateAndActivateMainWindow()
{
// Create window and set the title to the app name appended by the executing user.
_mainWindow = new Window() { Title = $"HouseMoney - {Environment.UserName}" };
// Enable desktop acrylic backround if supported.
if (DesktopAcrylicController.IsSupported())
{
_mainWindow.Content = new Microsoft.UI.Xaml.Controls.Grid();
_mainWindow.SystemBackdrop = new DesktopAcrylicBackdrop();
// Create a dispatcher queue controller if required.
/*if (DispatcherQueue.GetForCurrentThread() == null)
{
NativeMethods.DispatcherQueueOptions options;
options.dwSize = (uint)Marshal.SizeOf(typeof(NativeMethods.DispatcherQueueOptions));
options.threadType = NativeMethods.DQTYPE_THREAD_CURRENT;
options.apartmentType = NativeMethods.DQTAT_COM_STA;
NativeMethods.CreateDispatcherQueueController(options, out nint _);
}
// Initial configruation for the system backdrop.
_systemBackdropConfiguration = new SystemBackdropConfiguration() { IsInputActive = true };
switch (Current.RequestedTheme)
{
case ApplicationTheme.Light: _systemBackdropConfiguration.Theme = SystemBackdropTheme.Light; break;
case ApplicationTheme.Dark: _systemBackdropConfiguration.Theme = SystemBackdropTheme.Dark; break;
}
// Hanlde window activation event to set the correct backdrop state.
_mainWindow.Activated += (sender, args) => { if (_systemBackdropConfiguration != null) { _systemBackdropConfiguration.IsInputActive = args.WindowActivationState != WindowActivationState.Deactivated; } };
// On closing the window disconnect the controller and clean up.
_mainWindow.Closed += (sender, args) =>
{
_desktopAcrylicController?.Dispose();
_desktopAcrylicController = null;
_systemBackdropConfiguration = null;
};
// Enable the system backdrop on the main window.
_desktopAcrylicController = new DesktopAcrylicController();
_desktopAcrylicController.AddSystemBackdropTarget(_mainWindow.As<ICompositionSupportsSystemBackdrop>());
_desktopAcrylicController.SetSystemBackdropConfiguration(_systemBackdropConfiguration);*/
}
// Ready for activation.
_mainWindow.Activate();

The fix for this issue is in 1.3.1 that is now available. |

1.3.1 = 1.3.230502000 (built May 2, 2023) |
|
Crash is gone and content no longer needed, so this seems fixed to me 👍 |

Seems like for the new XAML Backdrop APIs to work you have to have both a xaml and a xaml.cs file?
Just doing it like this crashes the application with code 3221226107 (0xc000027b):
