C++/WinRT - InitializeComponent issue with XAML derived class in sub-namespace #7600

JaiganeshKumaran · 2022-08-13T14:13:54Z

Describe the bug

Original issue: microsoft/cppwinrt#1169.
Minimal repro: https://github.com/Jaiganeshkumaran/XamlIssueRepro.Cpp.

Having a XAML class deriving from another control like Button, rather than Page/UserControl, fails to compile, saying InitializeComponent is not a member. I've noticed that this only occurs when the type is inside a sub-namespace, that is sub-namespace of the project's root namespace.

Steps to reproduce the bug

Create a new XAML control in a sub-namespace.
Build the project.
See errors show up.

Hi, does this only repro in UWP? Are you using System Xaml / WinUI2, or are you using WinAppSDK / WinUI3? (looks like the link to your repro app is broken). Thanks!
