I am building a .net Maui Android app. I have no problem deploying my app to an Android emulator or real device when in Debug mode. However if I deploy in Release mode, the app crashes on load. The android device log, shows the following error,

Assertion at /__w/1/s/src/mono/mono/mini/aot-runtime.c:3678, condition `is_ok (error)' not met, function:decode_patch, module is unusable (GUID of dependent assembly Microsoft.EntityFrameworkCore.Sqlite doesn't match (expected 'DE191E13-E625-494C-862B-66ABDC9BC3C8', got '0C0A2DB6-8411-4D35-912B-740A5B7BC5CE')).

I had no problem running this in Release mode earlier in the development cycle. I have updated both Visual Studio and Microsoft.EntityFrameworkCore.Sqlite probably several times since I last tested in Release mode.

My project does reference a DbClassLibrary. Both projects reference the same version of Microsoft.EntityFrameworkCore.Sqlite, 6.0.9 which is the latest at the time of writing.

I have tried deleting the App from the Android device, cleaned my solution and re-published.

My Visual Studio specs are as follows:

    Confirmed there is something wrong with latest Visual Studio update. Just yesterday 2022-09-26 my app built in release mode deployed to a physical device worked. As soon as VS update, release build no longer works with the following error:

    module is unusable GUID of dependent assembly Microsoft.Maui doesn't match expected BF439B92-AABA-4CDA-BC93-F05A69484D20 995F4EB1-CF87-459A-85C1-A7632CF609E3

    I deleted the /bin and /obj folders and rebuilt the app. That solved the problem.
