title: Xamarin forms Android project TargetFrameworkVersion Error after update to Xamarin Forms 5
body: <p>I just updated to Xamarin Forms 5 and now I cannot compile my project.  I get the error message</p>
  <p>The $(TargetFrameworkVersion) (v9.0) is less than the minimum required $(TargetFrameworkVersion) for Xamarin.Forms (10.0). You need to increase the $(TargetFrameworkVersion)</p>
  <p>However, as you can see from the screen shot below, my Target Framework Version IS 10.  What am I missing??</p>
