I was working on an Android project using Xamarin in Visual Studio 2012. I recently upgraded from an HDD to a SSD so I reinstalled Windows and all of my programs.

adb uninstall did the trick. The strange thing is that even if you run the command to list all app that are installed it will not show up but if you run the uninstall command with ur package name which should be ur project name or name that you have assigned you will get the success result which means it got uninstalled and to check that if run the uninstall command again with same package name u will get failure command. Then deploying ur package again should work
