NavigateAsync, KnownNavigationParameters.UseModalNavigation & GoBackAsync about prism

[MartinRobins]

Just to add, I have included ...

UsePrism(prismAppBuilder=> {
  ...
  prismAppBuilder.ConfigureMopups();
  ...
{); 

I have based "SynchronisationPopupPage" on PopupPage as it is being ported from a Prism.Forms application. The documentation says it should be a drop in replacement so I have merely changed namespaces.

I am not using DialogService as the documentation says it is not supported in Prism 8.x

I have tried changing PopupPage to ContentPage (just to rule out Mopups); no difference. I still get the error and the modal page stays open.

@MartinRobins while I appreciate the lots of code you've provided here, we do require that you provide a sample that can reproduce the issue. I do not have time to create samples for everyone's issues.

[MartinRobins]

@dansiegel Please find attached a minimal VS2022 solution that demonstrates the issue.
When you run the application, follow the instructions on screen and you will see what to do in order to reproduce it.

Note: I have only seen (and tested) the issue on Android.

I am unable to reproduce your issue using net8 and Prism 9. Please be sure you are using the latest bits.

[MartinRobins]

@dansiegel Were you able to verify the problem in net7 and Prism 8 (as originally provided)?
If this is the case, then I can be confident that simply moving to net8/Prism9 (when they are released) will resolve the problem.

[dansiegel]

I do not bother with net7. We don't support net7 and this isn't paid support. If you require Paid support please feel free to reach out to us at [email protected] and we can discuss your options.

Sorry, did not realise .NET7 was unsupported. I do not yet have .NET8 (or the VS preview) so had not tested with this.
Thank you for your help; I will look into the available support options as I have always preferred using Prism with Xamarin in the past as, if nothing else, the navigation is so much easier.
