LINQ

I am trying to query a datatable via LINQ and my code is as follows - after reading on the google.

var result = from c in ods.Tables[0].AsEnumerable()
select new { c.Field<string> ("name")};

My problem is, i needs to import

system.data.datasetextensions

for this code to work, I was able to add the reference to this dll.

But when i do using System.Data, i do not get the datasetextensions name space options.


Kindly help me...am learning
