title: Use Windows Forms in a .Net Core Class Library - .NET Core Control Library
body: <p>I am trying to create a .net core 3 class library that references the .net core 3 version of winform (so this assembly can itself be referenced by a .net core 3 WinForm assembly).</p>
  
  <p>A new .net core WinForm project references Microsoft.WindowsDesktop.App.WindowsForms, however I can't find any nuget package with that name.  </p>
  
  <p>What do I need to do to reference the .net core 3 winform?</p>
