title: dotnet 5 and Xamarin Android: The imported project "Xamarin.Android.CSharp.targets" was not found
body: <p>I'm running on MacOs Apple M1 chip (ARM64 but using Rosetta 2):</p>
  <ul>
  <li>Rider 2020.3 EAP 10</li>
  <li>dotnet 5</li>
  <li>Xamarin Android plugin and SDK installed within Rider.</li>
  </ul>
  <p>When I open a Xamarin Android app solution, most of the code is red including statements like &quot;using System&quot; and I get the following build error:</p>
  <pre><code>The imported project &quot;/usr/local/share/dotnet/sdk/5.0.100/Xamarin/Android/Xamarin.Android.CSharp.targets&quot; was not found.
  </code></pre>
  <p>It seems to be related to dotnet 5 judging by that path. Anyone has a clue?</p>
