Hi

I am using Prism within my UWP app and one of my customers get the following exception:

Prism for UWP is not supported. Only WPF, XF, and Uno are supported at this time.

Hi Brian

Something felt not right...

I did create my UWP App with the Windows Template Studio extension in Visual Studio that helps developers to create UWP applications. It says that Windows Template Studio uses Prism 6.3 and that Prism doesn't support UWP from version 7 onwards

I find this a bit confusing... Is Prism 6.3 supported or is Microsoft making a mistake here?

All the best

We're encountering the same issue within a legacy UWP app utilizing Prism 6.3 on Windows 11, seemingly tied to suspend/resume functionality. Are there any known workarounds for this? Any insights would be greatly appreciated. Thank you.
