title: Xamarin.Forms install error message runaround
body: <p>I created a new Xamarin.Forms project and I am trying to upgrade the Xamarin.Forms Nuget package from 3.6 to v4.3. When I try to install a newer version I get a runaround of error messages that goes in circles. Here's how it goes:</p>
  
  <ul>
  <li>Right click on solution >Manage Nuget Packages</li>
  <li>Installed Tab >Xamarin.Forms. Shows v3.6 installed in all projects (main/shared project, Android, UWP)</li>
  <li>Select v4.3 and install upgrade to all projects</li>
  <li>Error: Error NU1107  Version conflict detected for Xamarin.Android.Support.Compat. Install/reference Xamarin.Android.Support.Compat 28.0.0.3 directly to project HPlusSports.Android to resolve this issue.</li>
  <li>I search for Xamarin.Android.Support.Compat, select v28.0.0.3 and install it directly into my Android project.</li>
  <li>Error: Error NU1107  Version conflict detected for Xamarin.Android.Support.Annotations. Install/reference Xamarin.Android.Support.Annotations 28.0.0.3 directly to project HPlusSports.Android to resolve this issue.</li>
  <li>I search for Xamarin.Android.Support.Annotations, select v28.0.0.3 and install it directly into my Android project.</li>
  <li>Error: Error NU1107  Version conflict detected for Xamarin.Android.Support.Annotations. Install/reference Xamarin.Android.Support.Annotations 28.0.0.3 directly to project HPlusSports.Android to resolve this issue.</li>
  </ul>
  
  <p>So I follow the instructions in the error messages but the error messages just go in circles. No matter what I try to install there is no resolve.</p>
