Once Admin privileges were restored, the project built without a problem. The process of installing the new VS apparently modified the shortcut so that the program no longer runs as Administrator - and I did not even notice that it wasn't asking permission any more. It always asks me for permission, and I always give it. I have that shortcut set up to launch the program as Administrator.

I launch Visual Studio from a shortcut in my task bar/start bar menu. It turns out that it's easy to miss the absence of something that you are used to doing as a matter of habit. Do I need to revert Visual Studio versions? I can't figure out who or what thinks this should need the newer version, nor how to convince it not to need it. I've tried switching the TargetFrameworkVersion to 9.0, (which I don't want anyway) and switching back, but no change. Add a reference to "MonoAndroid,Version=v9.0" in the "TargetFrameworks" property of your project file and then re-run NuGet restore.Īs far as I know, nothing in the project should want or need this version - and I don't want to just add a reference to it, to break it for everyone else. Your project does not reference "MonoAndroid,Version=v9.0" framework.

When I try to compile the project, I get the following error: I upgraded to Visual Studio version 15.8.0 (very recent at this point). Other developers are building the project as is from the source with no issue, and the TargetFrameworkVersion is set to v8.1. We have a Xamarin Forms project that I have worked on in the past, and to which I have recently returned.
