title: Yellow triangle symbol on Dependencies without error when use wildcards in the PackageReference
body: <p>I was recently learning about nuget, in the document <a href="https://docs.microsoft.com/en-us/nuget/reference/package-versioning#version-ranges-and-wildcards" rel="nofollow noreferrer">Version ranges and wildcards</a>, I tried this function:</p>
  
  <pre><code>&lt;PackageReference Include="AutoMapper" Version="6.*" /&gt;
  </code></pre>
  
  <p>But I noticed that there is a yuellow triangle symbol on Dependencies without error (I could not post the image directly here, since I have no enough reputation.)</p>
  
  <p><a href="https://i.stack.imgur.com/veQU2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/veQU2.png" alt="enter image description here"></a></p>
  
  <p>Nuget restore, clean up, restart VS, None of them resolve this issue.</p>
  
  <p>Reproduce steps:</p>
  
  <ol>
  <li><p>Create a .net core class library project.</p></li>
  <li><p>Add the nuget package AutoMapper 6.2.2</p></li>
  <li><p>Edit the project file, change the version from 6.2.2 to 6.*, save it.</p></li>
  </ol>
  
  <p>Appreciate your help!</p>
