[NET10.0] Unable to deploy basic template on ios/android in release mode

[PureWeen]

Description

I've tested this against preview7 and I tested this by putting the mauitemplate into our sandbox app.

dotnet new maui
dotnet build -t:run -f net10.0-android -c:release

I haven't been able to reproduce this locally. Have you tried, @StephaneDelcroix?

There's a good chance this was just on my machine.

Just wanted to make sure to get a couple folks to validate as well.

My local templates might be messed up

[StephaneDelcroix]

could you share your local template ? this still looks like a bug, related to coebehind-less resource dictionary that is created by reflection at runtime.

could you share your app as-is? this looks like a potential regression

[StephaneDelcroix]

not able to reproduce either. InitializeComponent is properly replaced. @PureWeen, please share a project whenever you can, but it might end up being just fine at the end

[simonrozsival]

Based on the code that @PureWeen sent internally, the problem is in this code:

<Style TargetType="ImageButton">
    <!-- ... -->
    <Setter Property="Background" Value="{AppThemeBinding Light={StaticResource LightBackground}, Dark={StaticResource DarkBackground}}"/>
    <!-- ... -->
</Style>

The Activator.CreateInstance swallows the original exception. We need to catch TargetInvocationException in ResourceDictionary.SetAndCreateSource and re-throw the inner exception.

Just got confirmation from CSI that we have test cases for this now. They weren't able to reproduce. So looks like there is still a bug to fix here, and we also now have validation that this scenario won't break
