I have created a local IIS copy of a website we have on our servers. when trying to build it in Visual Studio 2010 I get the following error:
Error 5 Method 'get_EnableCdn' in type 'System.Web.UI.ScriptManager' from assembly 'System.Web.Extensions, Version=220.127.116.11, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation. D:\Websites\EAA\config\splashes\noNodes.aspx 1
I did a search on the Umbraco forums and found the topic from John who had the same error and resolved it by changing the App_Pool target to .NET V2 rather than V4, however, this has not worked for me and the error persists.
Any idea what else could be the solution?
