Thanks, yeah it is C#/.net9 and WinUI3. I started with C#/WPF, but wanted to get it on the Windows Store and couldn't figure out that would work with WPF.
I don't mean to imply it's not possible, but I ran into issues packaging with Desktop Bridge and the web started pushing me toward extreme solutions, so I changed course. If there's a lesson here, it's to package early (and know what you are up against).
