  <p>Here's what I have done:</p>
  
  <ol>
  <li>Switch to PackageReference as default. Tools -> Options -> Nuget Package Manager -> General -> Default to PackageReference.</li>
  <li>Migrated nuget packages to PackageReference. Right-click reference and selected migrate to packagereference.</li>
  <li>Installed nuget for Microsoft <code>Microsoft.Toolkit.Forms.UI.Controls.Webview</code>. I was initially getting the error regarding PackageReference but the previous steps fixed it. </li>
  <li>I'm now getting the errors above, and they're all related to the Contracts nuget. I've installed and uninstalled this nuget with no results.</li>
  </ol>
