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.
I am able to do this with other file types including .cs, .css, .js, etc.
I have tried the suggestions in Open two instances of a file in single Visual Studio session including the registry edit and the custom keyboard shortcut without success. Is there a specific registry hack or some other solution for .aspx files?
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.
