Well, Entity Framework generates an ObjectContext for you. You should know the name of your ObjectContext class. Then to query using LINQ you can do something line that

using(var context = new NorthwindContext())
{
   var query = from p in context.ProductsSet select p;
   // then loop through your query instance.
}

The above example is very simple you should have a look at http://thedatafarm.com/blog/ for better tutorials
