I've created a bare-bones Xamarin app (with shared elements, but they're not doing anything yet). It builds and runs in debug mode just fine on UWP and Android (I don't have a Mac to build it for iOS). But I've had to move it to another drive - a simple copy of the whole project directory to the new location. Now the Android version builds and debugs ok, but the UWP version gives me the error:
DEP0700: Registration of the app failed. [0x80073CF0] error 0x80070003: Opening file from location: AppxManifest.xml failed with error: The system cannot find the path specified.
How can I find out what's missing and tell Visual Studio where to look for it? (The version in the original location still works fine, but I'll need to delete that when I get the version in the new location working.)
