Answer 1

hello,

As far as I know the class are case sensitive, have you tried the Microsoft.SharePoint.WebPartPages namespace?

Hello,

Make sure you have referenced Microsoft.SharePoint.dll that is located at your sharepoint folder at  C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI

Yes, namespace required is located in sharepoint.dll. You get sharepoint.dll instaled on a machine that has Sharepoint installed on it and is located at

  C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI 

know as  "14 Hive" folder.

Hi Ashok,

Please go to the references of your Visual Studio 2010 SharePoint Project, and find if the "Microsoft.SharePoint.dll" reference correctly. If not, you can delete it and re-reference it from this path" C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI".

Thanks,
