The composite design pattern allows you to set up a tree structure and ask each element in the tree structure to perform a task. A typical tree structure would be a company organization chart, where the CEO is at the top and other employees at the bottom.

Prior to arriving at my previous consulting assignment, the company had already completed their first WPF project. The architecture they used on that earlier project included a rather unusual, in my opinion, hybrid object/relational in-memory representation of business objects. Some of the business objects were wrapped in View Models, while the View was directly referencing ADO.NET data rows of other business objects. I initially kept an open mind, programming their new app to that earlier archi...

Factory Method Pattern creates an instance of several derived classes. Centralize creation of an object of specific type choosing one of the several implementations. It is called factory pattern as it is responsible for "manufacturing" an object. The Factory pattern is meant to give you the ability to generically construct objects rather than explicitly declare what you want to create vi...

Builder pattern falls under the Creational design pattern. The Builder pattern separates the construction phase of a complex object from its representation so that the same construction logic can be used for different objects and the output representation may be different.

Singleton and Prototype patterns fall under Creational Design Patterns which deal with object creation.

Singleton - The purpose of a Singleton pattern is to ensure that one and only instance of the class is present at any time. We usually create the instance of the object on demand i.e. delay loading and then ensure that once it is created, no more instances are allowed to be created....

When using ASP.NET AJAX Extensions to transition your site to an AJAX experience, there are two main programming models to choose from: partial rendering and script services. In last month's column, I discussed partial rendering from a primarily architectural perspective. Simply put, with partial rendering, you don't need to change the underlying architecture of an ASP.NET application—it's an easy route to implementing some of the best elements of AJAX, such as no-flicker updates to pages on you...

The bridge pattern decouples an abstraction from its implementation so the
two can vary independently. In other words we make a bridge between
the abstraction and its implementation and therefore we won't have a
binding between the two. The pattern helps us whenever we need to
select or switch the implementation at runtime....
