Android App Crashes Immediately on Start Up on Release or Debug not launched from the Debugger - unusable (GUID of dependent assembly Xamarin.AndroidX.AppCompat doesn't match

[davidlederman]

Android framework version

net9.0-android

Affected platform version

VS 2022 Version 17.14.16 Xamarin.Android SDK 13.2.2.0 (d17-5/45b0e14)

Description

I have an app that simply can only be run from the debugger. In release mode the app briefly shows the splash screen and immediately stops running. If you try Debug mode Debug->Start without Debugging, or tapping on the App Icon on the device it displays the same behavior.

I initially was getting the error being that Maui.Essentials GUID was wrong, after removing the dependency the issue moved to being 'Avalonia.Android.so' is unusable (GUID of dependent assembly Xamarin.AndroidX.AppCompat doesn't match (expected 'DFC8274A-39AB-468C-BFE7-7D7B58E91F7A', got '0542E451-C016-4FA2-B719-AD3ACDCC1B6D')).'

Steps to Reproduce

Run the app

Did you find any workaround?

No response

Can you attach a .binlog of a broken Release build? https://aka.ms/binlog

@davidlederman do you know if this happens with any Avalonia project? or just yours?

The general problem would be if some MSBuild task edited the .dll files after the <MonoAOTCompiler/> task runs. But I'm not seeing any of the tasks (that I know of) that do this in your .binlog.

I'm not aware if Avalonia has any custom build steps that cause this.
