XamlTypeInfo.g.c Trim and Obsolete Warning #10356
Description
Describe the bug
After enabling AOT compilation (<PublishAot>true</PublishAot>) in my WinUI 3 project, I encountered several warnings related to XamlTypeInfo.
'this' argument does not satisfy 'DynamicallyAccessedMemberTypes.PublicConstructors', 'DynamicallyAccessedMemberTypes.NonPublicConstructors' in call to 'System.Type.TypeInitializer.get'. The parameter 'instance' of method 'PSXMaster.PSXMaster_XamlTypeInfo.XamlTypeInfoProvider.get_127_Type_TypeInitializer(Object)' does not have matching annotations. The source value must declare at least the same requirements as those declared on the target location it is assigned to.
'Type.IsSerializable' is obsolete: 'Formatter-based serialization is obsolete and should not be used.'
'TypeAttributes.Serializable' is obsolete: 'Formatter-based serialization is obsolete and should not be used.'
when i double click on warning i navigated to this:
Steps to reproduce the bug
Create a WinUI 3 (Windows App SDK) project.
Enable AOT compilation by adding the following to the .csproj file:
<PublishAot>true</PublishAot>
Build the project.
Expected behavior
The XAML compiler should generate code that is compatible with AOT without triggering trimming-related warnings.
Obsolete serialization APIs should not be used in auto-generated code.
