Answer / Uma Shankar Prasad

"The three main components of LINQ (Language Integrated Query) are: 1. Query Operators: These are methods and extension methods that enable the manipulation of data collections. Examples include Where, Select, OrderBy etc. 2. Query Providers: These map queries to data sources like databases or collections in memory. There are four query providers shipped with .NET Framework - Entity Framework, LINQ to SQL, LINQ to XML and LINQ to Entities. 3. Extension Methods: These methods extend the functionality of existing classes without requiring the user to subclass those classes."n
