When using the latest DLL, I see some strange error on ie 11. The error will go away if I switch to ie 11 compatibility mode. But the it start to work fine after I installed the .net framework 4.5 on the server. My question is, if anyone know the UI for ASP.NET AJAX required .NET Framework 4.5 to be installed on the server in order for the application to work correctly with ie11?
