Steps to reproduce the issue:" ABP Suite - Use a 7.1 or 7.2 - Application template; UI Framework: Blazor Server; Mobile - Maui. Then run the Maui project (Not the MauiBlazor project) in Release mode. (You may need to select Deploy option for the maui project).
The MauiBlazor project runs fine. I believe it has something to do with Shell interaction with ABP. Spent days and days on this thinking it was something in my project, but I was able to duplicate with the abp template.

Couldn't see how to attach, so I created a public github for the project.

Could you hold off looking at this. I'm getting different results now. Some strange results, but different. I will update or close the ticket within a day.

ok,
Been able to narrow it down a bit further. Getting an error trying to use the string localizer now saying
MauiBlazorCachedApplicationConfigurationClient should be initialized before using it. -

Hi,
The
MauiBlazorCachedApplicationConfigurationClientwill initialize when the application starts.https://github.com/abpframework/abp/blob/dev/framework/src/Volo.Abp.AspNetCore.Components.MauiBlazor/Volo/Abp/AspNetCore/Components/MauiBlazor/AbpAspNetCoreComponentsMauiBlazorModule.cs#L41
I don't know the reason for the problem, How I reproduce the problem, could you provide the full steps? thanks.

I had commented out the below which was giving me these other problems. I uncommented it, removing those issues, but brings the original problem back again of not being able to run in Release mode.
app.Services.GetRequiredService<IAbpApplicationWithExternalServiceProvider>().Initialize(app.Services);I have verified again that the github repository I shared earlier in the ticket still has that problem and you can examine that.

Hi,
What's your steps?

Hi,
What's your steps?
1, Ensure that the Maui project and not the MauiBlazor project is the startup project. 2. Ensure that the run button is selecting an Android emulator or a local android device. 3. Change from Debug mode to Release mode. 4. Run project. 5. When it runs you will see the splash screen for a second or two, and then it disappears and the app crashes.

Hi,
It looks like a problem with MAUI.
You can try this:
[ContentProperty(nameof(Text))] public class TranslateExtension : IMarkupExtension<BindingBase> { public string Text { get; set; } = string.Empty; public string? StringFormat { get; set; } public BindingBase ProvideValue(IServiceProvider serviceProvider) { var l = ServiceLocator.Current.GetRequiredService<LocalizationResourceManager>(); var binding = new Binding { Mode = BindingMode.OneWay, Path = $"[{Text}]", Source = l, StringFormat = StringFormat }; return binding; } object IMarkupExtension.ProvideValue(IServiceProvider serviceProvider) => ProvideValue(serviceProvider); } public static class ServiceLocator { public static IServiceProvider Current => #if WINDOWS MauiWinUIApplication.Current.Services; #elif ANDROID MauiApplication.Current.Services; #elif IOS || MACCATALYST MauiUIApplicationDelegate.Current.Services; #else null; #endif } -

public static class ServiceLocator { public static IServiceProvider Current =>
#if WINDOWS MauiWinUIApplication.Current.Services; #elif ANDROID MauiApplication.Current.Services; #elif IOS || MACCATALYST MauiUIApplicationDelegate.Current.Services; #else null; #endif }
Yay, That worked! Thank you
