  <p><strong>What I have tried?</strong></p>
  <p><strong>1-</strong> I tried to delete <strong>bin</strong> and <strong>obj</strong> folders to force the project to rebuild everything, but the errors still appear</p>
  <p><strong>2-</strong> I tried to downgrade to <strong>16.4.4</strong> and <strong>the errors are gone</strong>, but I don't want to fix it by this way because I want to create a new other application using this <a href="https://docs.microsoft.com/en-us/visualstudio/releases/2019/release-notes#xamarin" rel="nofollow noreferrer">new feature in 16.7.0</a></p>
  <p>So, <strong>Is there a way to get rid of these errors without downgrade to the old version?</strong></p>
  <p><strong>Notes:</strong></p>
  <p>The version of Xamarin.Forms is 2.3</p>
