Bullet 4

The code in bullet 4 should ready:


// Check that the specified product exists
f (ProductExists (productNumber, database))
{
// Calculate the sum of all quantities for the specified product
stockLevel = (from pi in database.ProductInventories
join p in database.Products
on pi.ProductID equals p.ProductID
where String.Compare (p.ProductNumber, productNumber) == 0
select (int) pi.Quantity).Sum ();
}
}

(The code inside the if block in the book is from GetProduct method. CurrentStockLevel is being modified in this bullet.)

Type of error is an omission. Instructions should include a step for updating the source code in Program.cs file in the ProductsClient project to update the machine name in the following line of code:

proxy.ClientCredentials.Windows.ClientCredential.Domain = "LON-DEV-01";

to the reader's machine name. This should save the users a little bit of figuring out.
