Xamarin.UITest doesn't work with an app built with .NET 9

1) Error : SymbolCollector.Android.UITests.Tests.CollectSymbols
System.Exception : No .NET assemblies were found in the application. Please disable Fast Deployment in the Visual Studio project property pages or edit the project file in a text editor and set the 'EmbedAssembliesIntoApk' MSBuild property to 'true'.

But EmbedAssembliesIntoApk didn't help.

We are experiencing this as well.

.net-8.0 apk contains a folder called "assemblies" which contain the .NET assemblies

.net-9.0 apk does not contain this folder. Instead it appears the .NET assemblies have been moved into the lib folder under the name(s) libassemblies.{ARCH}-v8a.blob.so

Xamarin.UITest is probably looking in the wrong place for net9.0

@mattallscripts any work arounds you found?

[matt-architect]

Microsoft Support has indicated that this is not supported.

The only option we have is the run UI Tests on a .NET 8 version of the code and in the meantime get our tests converted to SpecFlow to support .NET 9

Have you @bruno-garcia found any other option in the meantime?

I nuked the old UITests, at first went with Android Instrumentation, working on Emulators.

But at the end went to Appium, since saucelabs doens't support Instrumentation with a single apk (and having 2 apks didn't really work during my tests due to mono runtime crashes)
