This Visual Studio extension enables developers to generate, test and publish App Attach ready packages. Currently, this supports WinUI3 SPP applications only.
We are introducing tooling enhancements within Visual Studio to get you creating App Attach ready packages right within your flow of work. Currently in preview, App Attach extension allows you to create VHD(x) images and publish them to AVD host pool right from within Visual Studio, enabling you to get started with MSIX App Attach much faster. You can also test your application by attaching it locally or just create App Attach ready packages for sharing externally.
