title: Open .aspx file in two windows in Visual Studio 2013
body: <p>I am trying to open the source view of one large .aspx file in two separate windows/tabs in Visual Studio 2013. The "Window > New Window" option is greyed out for this file type.</p>
  
  <p>I am able to do this with other file types including .cs, .css, .js, etc.</p>
  
  <p>I have tried the suggestions in <a href="https://stackoverflow.com/questions/728949/open-two-instances-of-a-file-in-single-visual-studio-session">Open two instances of a file in single Visual Studio session</a> including the registry edit and the custom keyboard shortcut without success. Is there a specific registry hack or some other solution for .aspx files?</p>
  
  <p>Just to clarify, I am not looking to "split" the file. My end goal is to have two copies of the file open in different vertical tab groups.</p>
