LINQ 09- LINQ Extensions

As we discussed earlier in "LINQ 08- IEnumerable", LINQ works with IEnumerable interface along with many extension methods. These extension methods are available in System.Core assembly in .Net Framework 4.0. You can find several extension methods available in the class System.Linq.Enumerable

 

So If you are going to use LINQ queries, you have to add System.Core as a reference and add “using Sytsem.Linq” to your imports.
