as i pointed out here Microsoft fixed that problem now
I have installed the lasted Ajax 1.0,and the ajax toolkit.
and my vs2005 has updated the sp1.
now,when i create a web application(not web site),if i use the toolkit as before,it dosen't works well.
the error message is "Sys not defined".
somebody said using Microsoft.Web.Extensions.dll.
but i can't find it in my computer,just a System.Web.Extensions.dll.
what can i do?
thank u!
Sys ist not defined have several reasons, most comon is missing scriptmanager on top of the page
With exactly the same problem I found the solution here: http://ajax.asp.net/files/Migration_Guide_Beta2_to_RC.aspx
Simply put, Microsoft.Web.Extensions.dll is renamed to System.Web.Extensions.dll. Tokens are the same.
The link in the last response no longer accesses a valid page. Can anyone point me to how I need to update my Web.config to handle Microsoft.Web.Extensions is now System.Web.Extensions. I tried to make changes but am still getting compile errors in regard to the validators and then asp:ScriptManager being an Unknown server tag 'asp:ScriptManager'.
This Problem can be caused by the application pool settings in IIS, if you leave as DefaultAppPool, will cause this, Set to Classic .NET appPool
