The Microsoft hotfix '2600088' definitely does NOT work, so you'll have to take the .browser file route.

With the latest version of IE11, you'll need to make a small revision to the ie.browser file RegEx posted by Sistemas-infoe above. Ensure you allow more characters in the UA string between the semi-colon and space. If your RegEx skills are terrible (much like mine), that's a period then a star.

NEW:

You can test if ASP.Net is recognizing the revision and the .browser file using:

Response.Write (Request.Browser.MajorVersion)

If that returns 11, your JS error should be gone. VOILA!

Update:

A second MS patch was released in October 2013. I was able to remove the .browser file now and simply use the patch. So far working well. - See http://support.microsoft.com/kb/2836939
