Differentiating between appx and msix packages
From a packaging perspective you don't really need to differentiate. The runtime will pick up currently based on the manifest declarations. It won't affected deployment since they share a common deployment stack. Think of a .appx as a really restrictive MSIX file. MSIX will light up new feature sets and includes out of band items like the package support framework.

As per the https://docs.microsoft.com/en-us/windows/msix/msix-1709-and-1803-support, MSIX is supported on Win 10 1709 and above. However APPX was supported on versions earlier than 1709 as well. Now there is no option to the manual tool (makeappx.exe) that guides it to generate MSIX or APPX.
How can I be indeed sure that I have generated a MSIX package and not an APPX package.
