Hmmmm...

Looks like they have improved the code a bit, I will give it an update: https://learn.microsoft.com/en-us/windows/uwp/monetize/request-ratings-and-reviews#show-a-rating-and-review-dialog-in-your-app

Any update on this? Xamarin support ends next week, so everyone is being forced to update to MAUI. Is this plugin dead?

[jamesmontemagno]

can you try 6.1.0-beta. i re-implemented it

[BurkusCat]

Thanks @jamesmontemagno for writing a new implementation

Immediately after updating the package, and trying it with my app I get this error:

Exception thrown: 'System.Runtime.InteropServices.COMException' in WinRT.Runtime.dll
WinRT information: This function must be called from a UI thread

Running it on the UI thread using either of the below options does not resolve the issue:

        await MainThread.InvokeOnMainThreadAsync(async () => await storeReview.RequestReview(true));
        MainThread.BeginInvokeOnMainThread(() => storeReview.RequestReview(true));

The review logic is being called from a service that decides when to prompt the user (as opposed to being activated on a button press).

[jamesmontemagno]

Hmmm it must be invoked on the UI Thread that is for sure.

These are the 2 lines of code that you must call from Windows, try to conditionally compile them and invoke with the dispatcher:

  var context = StoreContext.GetDefault();
 var result = await context.RequestRateAndReviewAppAsync();

[jamesmontemagno]

See: https://learn.microsoft.com/en-us/uwp/api/windows.services.store.storecontext.requestrateandreviewappasync?view=winrt-22621 it "should jus work"

I wonder if I have to do 👍

var hwnd = WinRT.Interop.WindowNative.GetWindowHandle(windowObject);
// Initialize the dialog using wrapper funcion for IInitializeWithWindow
WinRT.Interop.InitializeWithWindow.Initialize(context, hwnd); 

[jamesmontemagno]

Alright in 6.1.1-beta try this:

#if WINDOWS  
var hwnd = ((MauiWinUIWindow)App.Current.Windows[0].Handler.PlatformView).WindowHandle;  
StoreReviewImplementation.WindowObject = hwnd;
#endif  

then call it on UI thread

1. This didn't work ❌:

#if WINDOWS
        Application.Current.MainPage.Dispatcher.Dispatch(async () =>
        {
            var context = StoreContext.GetDefault();
            var result = await context.RequestRateAndReviewAppAsync();
        });
#endif

2. Works with window handle ✅:

   #if WINDOWS
       Application.Current.MainPage.Dispatcher.Dispatch(async () =>
       {
           var context = StoreContext.GetDefault();
   
           var hwnd = ((MauiWinUIWindow)App.Current.Windows[0].Handler.PlatformView).WindowHandle;
           WinRT.Interop.InitializeWithWindow.Initialize(context, hwnd);
   
           var result = await context.RequestRateAndReviewAppAsync();
       });
   #endif

3. Works without dispatcher (it appears it is not necessary)✅:

   #if WINDOWS
       var context = StoreContext.GetDefault();
   
       var hwnd = ((MauiWinUIWindow)App.Current.Windows[0].Handler.PlatformView).WindowHandle;
       WinRT.Interop.InitializeWithWindow.Initialize(context, hwnd);
   
       var result = await context.RequestRateAndReviewAppAsync();
   #endif

The 6.1.1-beta package is probably still processing so I will try your latest comment with it when its ready.

[jamesmontemagno]

Perfect! yeah with my changes it should work as it is the same code you have basically :)

Thanks for checking this, i appreciate it.

[BurkusCat]

Unfortunately, trying out 6.1.1-beta with the following code:

#if WINDOWS
        var hwnd = ((MauiWinUIWindow)App.Current.Windows[0].Handler.PlatformView).WindowHandle;
        StoreReviewImplementation.WindowObject = hwnd;
        await storeReview.RequestReview(true);
#endif  

I get these exceptions:

Exception thrown: 'System.InvalidOperationException' in WinRT.Runtime.dll
Exception thrown: 'System.TypeInitializationException' in WinRT.Runtime.dll
Exception thrown: 'System.Reflection.TargetInvocationException' in WinRT.Runtime.dll
Exception thrown: 'System.Reflection.TargetInvocationException' in WinRT.Runtime.dll

I've took a look at your branch it looks like what I actually need to be doing is passing the Window object:

#if WINDOWS
        var windowObject = (MauiWinUIWindow)App.Current.Windows[0].Handler.PlatformView;
        StoreReviewImplementation.WindowObject = windowObject;
        await storeReview.RequestReview(true);
#endif  

This works well 👍 Thank you for making these changes :)

[jamesmontemagno]

Oh perfect! Yeah i think having folks pass me the window will make the most sense. I think i will null it out after as well so it doesn't hang on to stuff.

I will change it to Window
