Yesterday I tried to add the Ajax Control Toolkit to my solution, i first had some problems because I used the version for .NET 4.0, so i replace it and used the version made for .NET 3.5.
I only added this lines :
To add a calendar control to my page. The problem is that now i have a server error Server Error in '/' Application. Runtime Error
And I don't get it to show the stack, i tried modifying the web.config, but it seems that the changes are not changing anything.
Does anyone have any idea ?
Thanks
EDIT : Even if i take the line i added back i have the same issue, i deleted the ajaxcontroltoolkit.dll of the references, retracted the solution and redeployed it, and i still have the same problem ...
EDIT2 : I just saw where the problem is the tag <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %> It seems that the assembly is not loading in the GAC ... I can't find it in the assembly folder
