About the application:

This example is used to demonstrate the MVC Pattern in .NET using C#/WinForm.

Here a simple application which is organized according the the Model-View-Controller(MVC) pattern.

The application displays a list of contacts and allows you to add, modify, and delete existing contacts.

The idea is to separate the user interface into View (creates the display) and Controller (responds to user requests, interacting with both the View as necessary).

The main advantage of MVC pattern is Loose Coupling. All the layers are separated with their own functionality. It is easy to replace a layer with some other type of layer so in other words, MVC pattern is to break up UI behavior into separate pieces in order to increase reuse possibilities and testability.

The main advantage of using the MVC Pattern is that it makes the code of the user interface more testable.

It makes a very structured approach onto the process of designing the user interface, which in itself contributes to writing clean, testable code, that will be easy to maintain and extend

The Model-View-Controller is a well-proven design pattern to solve the problem of separating data (Model) and user interface (View) concerns, so that changes to the user interface do not affect the data handling, and that the data can be changed without impacting/changing the UI. The MVC solves this problem by decoupling data access and business logic layer from UI and user interaction, by introducing an intermediate component: the controller.

This application you can store your customers' contact information. The application displays a list of contacts and allows you to add, modify, and delete existing contacts (deleting multiple existing contacts at once). All customers have an ID, First Name, Last Name and Sex. The screen that operator of this app uses to maintain his list of customers. After a new user is added, his ID cannot change anymore because is a generated unique GUID!
