Q: Desktop5 vs Desktop7 Context Menus

Hi TIMOTHY_MANGAN,  

Desktop4, and 5 should be all that is needed to get a context menu item registered on both Win 10 and 11. The underlying implementation of the context menu handler will be IExplorerCommand, not IContextMenuHandler. Below is a snippet of what the appxmanifest may look like.

It works for both fully packaged and Sparse Manifested apps.
