Something about pages in one of my web apps causes Visual Studio to add entries named "blank" under the page name in Solution Explorer under a "Script Documents" node. All this only appears once debugging starts and disappears if I close the page where this happens. New entries are added about every 6 seconds, so that after just a few minutes running in the debugger I have to scroll through multiple pages in the Solution Explorer just to get to the actual code, and then if the entry is added as I'm clicking, I open the wrong document. Not helpful!

These documents all contain this script, and nothing else:

I haven't used JQuery. Searching the project for terms like "trywebsockets" and "disconnecttimeout" that appear above returns nothing. The only reference I could find online was on MSDN (https://social.msdn.microsoft.com/Fo...?forum=vsdebug) and MS never suggested a solution.

As best we can determine, VS is generating this. But where?
