title: Bitmap not found in System.Drawing in Unity3D
body: <p>Maybe just an oversight on my part, but I can't make sense of this:</p>
  
  <ul>
  <li>I have the reference to System.Drawing in my project tree within the references</li>
  <li>I have the correct using statement <code>using System.Drawing;</code></li>
  <li>I can access other members of this namepace</li>
  <li><a href="https://docs.microsoft.com/en-us/dotnet/api/system.drawing.bitmap?view=netframework-4.8" rel="nofollow noreferrer">According to the docs, bitmap should be within this namespace.</a></li>
  </ul>
  
  <p>However, if I try use a bitmap, I get the following error:</p>
  
  <blockquote>
    <p>Error CS0246  The type or namespace name 'Bitmap' could not be found
    (are you missing a using directive or an assembly reference?)</p>
  </blockquote>
  
  <p>VS19-IntelliSense suggests to install the package <code>System.Drawing.Common</code>, however if I do that, I get yet another error, stating:</p>
  
  <blockquote>
    <p>The type name 'Bitmap' could not be found in the namespace
    'System.Drawing'. This type has been forwarded to assembly
    'System.Drawing. </p>
  </blockquote>
  
  <p>How can I resolve this issue to actually use the <code>Bitmap</code> class?</p>
