Question

I’m reading Jon Skeet’s book and he offers a great example:

List<Product> products = Product.GetSampleProducts();

foreach (Product product in products.Where(p => p.Price > 10))
{
    Console.WriteLine(product);
}

This seems pretty straightforward to me. But, when I try to do the same, the Where does not show up in the intellisense. Am I missing something? It looks the same.

List<lead> prospects = GetAllProspects();

foreach (lead prospect in prospects)
{

}

Add a reference to System.Linq:

using System.Linq;

Make sure your project is targeting .Net 3.5 or greater.
