We have used Click Once “Online Only” to download our WPF application for years. It’s made in .net framework 4.7.1 using x86.
Today I installed two new Asus Vivobook PC’s coming with Windows 11. I made a shortcut that points to the .application file in Azure and that usually works, but not today. It downloaded the file just okay, but instead of opening it, it pointed to Store to find an application to open it with. I didn’t see that as an option.
