title: VS2019: How to resolve the "unknown sub-lang: 0x8" message in Resource View?
body: <p>I have recently started using Visual Studio 2019 for my C++11 project. VS2019 converted the project and it compiles into an executable. But I can't open my resource (.rc) file in the Resource Viewer. It gives me this warning:</p>
  
  <blockquote>
    <p>A resource in this file uses an unknown language: Neutral (Default)
    (unknown sub-lang: 0x8). Unable to open this file.</p>
  </blockquote>

  <p>I tried trimming the resource file to bare necessity but that did not work.</p>
  
  <p>The strange thing is that it also happens with Scribble, Microsofts example project. I downloaded it from <a href="https://docs.microsoft.com/en-us/cpp/mfc/walkthrough-updating-the-mfc-scribble-application-part-1?view=vs-2019" rel="noreferrer">https://docs.microsoft.com/en-us/cpp/mfc/walkthrough-updating-the-mfc-scribble-application-part-1?view=vs-2019</a> using the [Scribble 1.0 MFC sample] link under the Prerequisites header.</p>
  
  <p>When the solution is opened in VS2019, it is converted, it compiles, but I can't open the accompanying resource file to look at the Dialogs.</p>
  
  <p>Any help is appreciated!</p>
  
  <p>Best regards,
  Keun</p>
