Overview of ASP.NET MVC Framework

Overview of C# .NET MVC

What is ASP.NET MVC?

• A web application framework developed by Microsoft
• Built on top of ASP.NET
• Follows the Model-View-Controller (MVC) pattern

Key Components of ASP.NET MVC

Model

• Represents the application's business logic and data
• Typically consists of classes that encapsulate data and behavior
• Can be entity framework, database, or any other data repository

View

• Responsible for rendering the user interface
• Typically consists of HTML, CSS, and JavaScript
• Can be Razor, ASPX, or other templating engines

Controller

• Acts as an intermediary between the Model and View
• Receives input, interacts with the Model, and updates the View accordingly
• Typically consists of classes that inherit from the Controller class

Request Life Cycle in ASP.NET MVC

1. Request: Client sends a request to the ASP.NET MVC application
2. Routing: The request is routed to the appropriate Controller and Action
3. Controller: The Controller receives the request and interacts with the Model
4. Model: The Model retrieves or updates data as necessary
5. View: The Controller passes data to the View, which renders the UI
6. Response: The rendered View is sent back to the client as the response

Routing in ASP.NET MVC

Route Configuration

• Defined in the RouteConfig.cs file
• Uses the MapRoute method to define routes
• Can be customized to handle different types of requests

Route Types

• Default Route: controller/action/id
• Custom Route: Can be defined using attributes or route templates
• Attribute Routing: Uses attributes to define routes on actions or controllers

Advantages of ASP.NET MVC

• Separation of Concerns: Clean separation of business logic, presentation, and data
• Reusability: Components can be reused across the application
• Testability: Easy to write unit tests for individual components
• Flexibility: Can be used with a variety of databases and frameworks
