Hi,
as a result of migrating from xamarin to .NET MAUI, using the migration tool “Upgrade Assistant” provided by microsoft, I have resolved the various errors related to solution compilation.
The code compiles correctly and even manages to emulate on physical device but as soon as the app is launched on the device, the app closes without giving any error or exception.
Trying to make a build of the solution, visual studio does not detect any kind of error and tries to emulate the app correctly on the device or emulator. (The above behavior occurs with physical android device and emulator)
Can you please give us support?
Thank you,
Mattia

I used the same version to test on an Android device. This crash did not occur.
The Upgrade Assistant cannot complete all migration tasks. According to the Next Step of the migration document, you need to make some manual changes to the project.
