Behavioral design patterns are design patterns that identify common communication patterns between objects and realize these patterns. By doing so, these patterns increase flexibility in carrying out this communication. Behavioural Patterns Mediator:- Defines simplified communication between classes. Memento:-Capture and restore an object’s internal state. Interpreter: – A way to include language elements in a program. [...]

Structural Design Patterns
Structural design patterns are design patterns that ease the design by identifying a simple way to realize relationships between entities. In this tutorial you will learn about Structural Patterns – Adapter, Bridge, Composite, Decorator, Facade, Flyweight and Proxy. Structural Patterns Adapter:-Match interfaces of different classes. Bridge:-Separates an object’s abstraction from its implementation. Composite:-A tree structure [...]
Creational Design Patterns
Creational design patterns are design patterns that deal with object creation mechanisms, trying to create objects in a manner suitable to the situation. In this tutorial you will learn about Creational Design Patterns, Factory Method, Abstract Factory, Builder, Prototype and Singleton. Creational Patterns (all about creation of objects) Factory Method: – Creates an instance of [...]
All about patterns
A pattern describes a recurring problem that occurs in a given context and, based on a set of guiding forces, recommends a solution. The solution is usually a simple mechanism, a collaboration between two or more data objects, services, processes, threads, components, or nodes that work together to resolve the problem identified in the pattern. [...]

WPF Introduction
The Windows Presentation Foundation (or WPF) is a graphical subsystem for rendering user interfaces in Windows-based applications. WPF, was initially released as part of .NET Framework 3.0. Designed to remove dependencies on the aging GDI subsystem, WPF is built on DirectX, which provides hardware acceleration and enables modern UI features like transparency, gradients and transforms. [...]
Prism 2.0
Composite Application Guidance, affectionately known as Prism, version 2 was released in oct 2009. Prism provides guidance and code that can help you build modular applications that can adapt to constant changing requirements. Prism guidance is a set of tools, samples, references and written guidance to help you more easily build modular applications. Generally the “modular” [...]
Design patterns
What are Design patterns ? In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn’t a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many [...]
