Hi All,
I have a website on asp.net4.0. I wish to use Ajax Control ToolKit but it is giving compilation error

Quote:
Error 20 The type 'System.Web.UI.ExtenderControl' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

I did following to install AjaxControl Toolkit
1) Installed NuGet
2) Installed AjaxControlToolKit using NuGet Console in Visual Studio 2010
Install-Package AjaxControlToolKit

Hi,

Ensure that you have reference to System.Web.Extensions as your error says...
