Worked on the dotnet/wpf repository to enhance deployment reliability for WPF applications by addressing a critical packaging issue affecting self-contained publishes. Focused on build automation and packaging, the developer used C#, C++, and XML to ensure ijwhost.dll was correctly included as a native asset under the appropriate runtime directory, rather than being misplaced in the managed library folder. Centralized the packaging logic within Packaging.targets, improving maintainability and reducing future migration risks, particularly for mixed-mode C++/CLI assemblies. This work resolved missing binary issues in self-contained deployments, resulting in more consistent release cycles and a smoother experience for end users.
