Ramesh Maruthi · Answer

instead of using .Add()use .AddObject() and instead of using .Remove use .DeleteObject().. The add and remove are from EntityFrame namespace System.Data.Entity so my guess is using System.Data.Entity missing ? Also check reference EntityFramework.dll added in project ? Or use package manager (nuget) to get EF added in project? Does your context derive from DBContext ? If not No add. If you see AddObject you are most likely deriving from ObjectContext instead
