Application Life Cycle Starts when the application runs. Application_Start() initializes global settings. Request Life Cycle Begins when a user sends an HTTP request. Steps: Routing → URL maps to controller. Controller Initialization → Controller is created. Action Execution → Action method is called. Result Execution → ViewResult is returned. View Rendering → View is rendered into HTML. Response Sent → HTML sent to browser.

Cynthia Sathuragiri · Answer

When a user sends a request, the application starts and sets up routing. The routing engine checks the URL and decides which controller and action to call. The MVC handler creates the right controller based on the route. The controller runs the action method to process the request. The action returns a result, usually a view. The view is rendered into HTML using Razor. The HTML is sent back to the user's browser as a response.

The MVC application life cycle in .NET can feel like a black box at first, but once you understand the key steps, it all clicks into place. Here's a simplified breakdown: 1. Application Start: Everything begins in Global.asax with the Application_Start() method. This is where routes are registered (RouteConfig.RegisterRoutes) and other one-time setup tasks are performed. 2. Routing: When a request comes in, the routing engine checks the URL pattern and maps it to the appropriate controller and action method using the route table. 3. MVC Handler Execution: Once a match is found, the request is handed off to MvcHandler, which initializes the controller via the controller factory. 4. Controller Initialization: The controller is created, and the appropriate action method is invoked. This is where your actual business logic happens — pulling data from services or databases, etc. 5. Action Execution : The action returns an ActionResult (like ViewResult, JsonResult, etc.). This is abstracted so you can return views, JSON, files, or redirects. 6. Result Execution: Finally, the ActionResult executes — for instance, rendering a Razor view and sending the HTML response back to the browser. It’s a clean separation of concerns and works well for both large-scale enterprise applications and smaller modular builds. Especially when paired with dependency injection and clean architecture practices, MVC in .NET is still quite powerful.
