Abstract: This is a quite simple design pattern, let me tell you one thing there are many design patterns that they are implicitly singletons. I rather recommend to understanding this one first before going through other patterns. There are many cases that we need only one instance of the object through-out the application, may be specific scope like user specific and the class should not allow the users or other classes creating object on their own. Apart from one instance, the same object should provide or control the creation of object and provide the instance to anyone who requires that object.

Abstract: In this section we will discuss how we can make plug & play architecture using policy application blocks. What we will do is we will take a practical scenario where we want to enable logging for an application depending on situations.

Abstract: When we consume business objects in UI, the logic can become pretty complex for activities like setting the business object value, getting the object value and setting the user interface from the object value. We can minimize the complexity of UI interaction with the business object using mediator pattern.

Abstract: In the same article we also discussed about how Windsor can be used to solve this problem. In this article we will take up a simple example and try to implement DI using unity application blocks thus resulting in loosely coupled architecture.

Abstract: In this tutorial we will try to understand how we can use interfaces and factory pattern to create a truly decoupled architecture framework. In this sample we will take up a simple three tier architecture and apply interfaces and factory pattern to see how we can transform the three tier in to a truly decoupled architecture.

Abstract: In this article we will discuss about how IOC and DI can help us build loosely coupled software architecture. I am not sure should we call this a design pattern or more of a approach. If you search around the web you will see lot of controversy on whether IOC is a design pattern or not. From my point of view it is a design pattern as it solves a problem context.

Abstract: Ask any developer which is the best place in a .NET class to clean unmanaged resources?, 70% of them will say the destructor. Although it looks the most promising place for cleanup it has a huge impact on performance and memory consumption. Writing clean up code in the destructor leads to double GC visits and thus affecting the performance multifold times.

Abstract: One of the important factors for performance degradation in .NET code is memory consumption. Many developers just concentrate on execution time to determine performance bottle necks in a .NET application. Only measuring execution time does not clearly give idea of where the performance issue resides
