Is there a clean example of desktop app navigation in MS Windows App SDK 1.0

If such exists, I'm batting 0.000 finding it. Something which works on a desktop app, without shoehorning UWP classes into it, and builds under current VS2022 using documented references and usings. Preferably with enough examples to cover menubars, breadcrumbs, navigate to-go back, open nonmodal page in new window, persisted vs reconstructed pages, and even modal popup windows. My hunting gets me a mixed mess of UWP, Xamarin, WPF, WINUIx, etc. none of which seem to work in WINUI3/WINAPPSDK (what is RootFrame! ;/ ), so I think we need a clear document describing best practices, even if it just advocates 3rd party/roll-your-own approaches.

The XAML Controls Gallery has many good examples (it is the UWP version of WinUI 3 Controls Gallery, but the code is the same (I even used it in VB.NET))

Thank you castorix! I did see several gallery apps and tried to build this one and got errors (I don't remember if they were build-time or run-time, regardless I downloaded the store version and studied it, and also tried to copy and paste fragments into an app with issues). I didn't keep a history, but I think I ran into differences between UWP and WinAppSDK, and didn't try long enough to figure them out. Also I was looking for basic pulldown menu behavior, not a Metro experience. I thought (perhaps wrongly) that UWP APIs were outdated and should be avoided. Since then, I've realized some fixes are as simple as changing windows.ui.xaml.something to microsoft.ui.xaml.something. I still say the best way forward isn't clear enough, especially for a xaml-newbie like me. Backing up, I feel some fundamental working docs are still needed. And maybe some clear marking of to which UI framework(s) each class/example applies.

Yes, it is in the doc : Migrate from UWP to the Windows App SDK
I usually just do that and I can copy/paste blocks of XAML without problem

I have found the samples in this blog very helpful in getting started with WinUI 3:
