Design Pattern Tutorials

Design patterns provide general solutions or flexible way to solve common design problems. This article provides a simple introduction regarding learning and understanding design patterns.
Before starting with design patters in .Net let's understand what is meant by design patterns and why is it useful in software programming.

What are Design Patterns in software development?
Design Patterns in the object oriented world is reusable solution to common software design problems that occur repeatedly in real-world application development. It is a template or description for how to solve problems that can be used in many situations. "A pattern is a recurring solution to a problem in a context." "Each pattern describes a problem that occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice." - Christopher Alexander, A Pattern Language. Patterns are used by developers for their specific design to solve their problems. Pattern choice and usage among various design patterns depends on individual need and their problem. Design patterns are a very powerful tool for software developers. It is important to understand design patterns rather than memorizing their classes, methods and properties. It is also important to learn how to apply patterns to specific problems to get the desired result. This will be the required continuous practice for using and applying design patterns in day to day software development. First identify the software design problem then see how to address these problems using design patterns and determine the best suited design problem to solve the problem. There are 23 design patterns, also known as Gang of Four (GoF) design patterns. The Gang of Four are the authors of the book, "Design Patterns: Elements of Reusable Object Oriented Software".
