I have installed my Hello World application using an MSI that I created for it. I've since converted the MSI installer to an AppX installer. Is it possible for the AppX installer to detect an existing installation of my Hello World application installed by the MSI installer and remove it, much as a standard MSI upgrade installation would?
I try to sideload one app in local machine twice， and I find when you sideload this app for the second time, the Appx installer can detect an existing app and remove the previous installation.
But it may not remind you that this app has been installed, and it doesn't also ask you that you wan to remove this app to reinstall or not, it just removes this app and reinstall app.
Update：I think it is impossible for the Appx installer to detect an existing installation of your application installed by the MSI installer and remove it. I install appx and there is no any detection information , and it will not remove the application installed by MSI installer
