Hello Joe, Object initializers let you assign values to any accessible fields or properties of an object at creation time without having to invoke a constructor followed by lines of assignment statements. The object initializer syntax enables you to specify arguments for a constructor or omit the arguments (and parentheses syntax). Consider this simple Car class class Car { public string Name { get; set; } public Color Color { get; set; } } object initializer syntax: Car car = new Car { Name = "Chevrolet Corvette", Color = Color.Yellow }; As you can see, we use a set of curly brackets after instantiating a new Car object, and within them, we have access to all the public properties of the Car class. This saves a bit of typing, and a bit of space as well. The cool part is that it can be nested too. Consider the following example, where we add a new complex property to the Car class, like this: class Car { public string Name { get; set; } public Color Color { get; set; } public CarManufacturer Manufacturer { get; set; } } class CarManufacturer { public string Name { get; set; } public string Country { get; set; } } object initializer syntax(Nested): Car car = new Car { Name = "Chevrolet Corvette", Color = Color.Yellow, Manufacturer = new CarManufacturer { Name = "Chevrolet", Country = "USA" } }; You can also dive into deep on below urls http://msdn.microsoft.com/en-us/library/bb384062.aspx http://msdn.microsoft.com/en-us/library/bb385125.aspx
