You've included the Generic namespace.

Change;

C#

public List GetBooks ()
{
    List list = new List();

    list.Add(new Book(101, "Java", 34.99));
    list.Add(new Book(102, "HTML", 31.99));
    list.Add(new Book(103, "XSLT", 37.99));
    list.Add(new Book(104, "XML", 59.99));
    list.Add(new Book(105, "XHTML", 35.99));
    list.Add(new Book(106, "CSS", 35.99));

    return list;
}

To

C#

public List<Book> GetBooks ()
{
    List<Book> list = new List<Book>();

    list.Add(new Book(101, "Java", 34.99));
    list.Add(new Book(102, "HTML", 31.99));
    list.Add(new Book(103, "XSLT", 37.99));
    list.Add(new Book(104, "XML", 59.99));
    list.Add(new Book(105, "XHTML", 35.99));
    list.Add(new Book(106, "CSS", 35.99));

    return list;
}

Hope this helps,
Fredrik
