AOP

                        Aspect oriented Programming

Today I would be discussing about AOP. what do we mean by AOP

   AOP

• Software development technique
• Allows to add enterprise functionality 
• Reduce boiler plate code
• Increase modularity
• Manage cross cutting concerns
• Infrastructure composition
• Wrapper around piece of business functionality

   AOP helps implement following principles

• Single responsibility principle
• Decorator pattern
• Open close principle
• Interceptors

  Advantages of AOP

1. Allows us to take common functionality within our applications, centralize it into singly responsibility.Attach these modules,  also known as aspects to     many places in the  application.
2. Most often aspects are encapsulating functionality that spends large         portion  of the application
3. Common cross cutting functionality includes Logging, security, profiling and transaction management 

    ASPECTS

     Where can we add these aspects or inspect or execute code?

•  OnStart: Executed immediately prior to the method call
•  OnSuccess :Executed immediately after the method call runs without                throwing an exception

   Types of aspects

           Calls to class methods/properties. These usually involves IOC                    Containers
