Bug:Build failure due to namespace changes in XamlTypeInfo after C++/WinRT update

[takatsuka2022]

Version

2.0.240111.5

Summary

I'm experiencing a build failure when referencing a WinUI 3 runtime component (root namespace: Control1) in a WinUI 3 project (root namespace: App1). The namespaces registered in App1's XamlTypeInfo are different before and after updating C++/WinRT.

Before the update, the entry in XamlTypeInfo looks like this:

L"Control1.UserControl1", L"",
&ActivateType<::winrt::Control1::UserControl1>, nullptr, nullptr, nullptr,
121, // Microsoft.UI.Xaml.Controls.UserControl
85, 0, -1, TypeKind::Metadata,
TypeInfo_Flags_None,
-1,

After the update, it changes to:

L"Control1.UserControl1", L"",
&ActivateLocalType<::winrt::Control1::implementation::UserControl1>, nullptr, nullptr, nullptr,
121, // Microsoft.UI.Xaml.Controls.UserControl
85, 0, -1, TypeKind::Custom,
TypeInfo_Flags_IsLocalType | TypeInfo_Flags_None,
-1,

This change seems to be causing the build to fail. Could anyone help me understand how to resolve the build issue?
