title: Windows Forms GUI beside .NET Core libraries Is it possible?
body: <p>I have some libraries that was written in .NET Core </p>
  
  <p>Can I use these libraries in Windows Form Application ?</p>
  
  <p>Can I reference them to my Win Forms or WPF ?</p>
  
  <p>In general Can I use .NET Framework beside .NET Core ? </p>
  
  <p>because I want to migrate to .NET Core but I need GUI for my Projects too and currently .NET Core does not support it</p>
  
  <p><strong>@JonSkeet</strong> ask me Do you test it ?
  Yes I test a very simple dotNETCore with my WinForm GUI</p>
  
  <p>in dotNET Core</p>
  
  <pre><code>public class Person
  {
      [EmailAddress]
      public string Name { get; set; }
  }
  
  public static class TestCore
  {
      public static string Get()
      {
          var type = typeof(Person).GetProperty("Name");
          var attr = type.Attributes;
          return attr.ToString();
      }
  }
  </code></pre>
  
  <p>I use reflection because Reflection namespace changed in it</p>
  
  <p>so I call Get() method in my GUI with button click. but show me an error</p>

  <p>seems something is wrong but I hope that I can use .NET Framework and dotNET Core together because we dont have any GUI solution yet !</p>
  
  <p>I hope MICROSOFT work on .NET Core version of WPF.</p>
