Problem
I have an ASP.net 4.0 application running on Windows Server 2003. I am running Windows 8.1 preview with IE 11 and I am getting the __dopostback undefined error. I have already tried all of the suggested hotfixes, kbs, and nuget packages and none of them work. I can add the site to the compatibility view settings and everything works fine. I googled but I cannot find any updated browser definition files for IE 11. Has anyone seen updated files or know what I can do to solve the problem. Like I have said I have already tried everything from this Scott Hanselman's blog article. So please do not post that as a response.
