  Accepted answer

  Before delving into the differences between MVC.NET and MVC.NET Core, it is important to first understand the distinction between .NET Framework and .NET Core. These foundational differences directly influence how the two MVC versions operate.

  Yes, there are differences in the page life cycle between MVC.NET (based on the .NET Framework) and MVC.NET Core (part of .NET Core). These differences arise due to architectural changes and design philosophies between the two frameworks.

  Page Life Cycle Comparison

  Aspect	MVC.NET	MVC.NET Core
  Request Processing	Tightly integrated with the System.Web pipeline (ASP.NET). Uses the ASP.NET Page Life Cycle which includes stages like BeginRequest, AuthenticateRequest, AuthorizeRequest, etc.	Built on ASP.NET Core Middleware pipeline. A modular approach using Startup.cs and middleware for request handling.
  Handler Invocation	Relies on the ControllerFactory to create controllers and invoke actions.	Uses Routing Middleware to map requests to controllers and actions.
  Events	Events like Application_Start, Session_Start, and Application_End are available in Global.asax for lifecycle management.	Eliminates Global.asax. Lifecycle events are handled in Startup.cs via ConfigureServices and Configure.
  HTTP Modules & Handlers	Uses HTTP Modules and Handlers for customizing the pipeline.	Replaced with Middleware for greater flexibility and composability.
  Session State	Managed by the System.Web pipeline with options for InProc, StateServer, or SQL Server.	Session is optional and configured explicitly via middleware.
  Filters	Supports Action Filters, Authorization Filters, Result Filters, and Exception Filters through attributes.	Similar filter types are available but enhanced with dependency injection and extensibility.
  Dependency Injection	Requires third-party libraries for DI integration.	Built-in dependency injection system simplifies controller lifecycle and dependency resolution.
  Action Execution	Lifecycle involves Controller.Execute, followed by action filters, model binding, and result execution.	Streamlined execution pipeline with middleware-driven execution and enhanced extensibility.
  View Rendering	Tightly coupled to the Razor View Engine.	Razor View Engine remains, but it is decoupled and can work alongside other templating engines.

  Key Differences

  1. Middleware Over System.Web Pipeline:

     • MVC.NET Core replaces the rigid System.Web pipeline with a middleware-based approach, making the life cycle more flexible and modular.
     • Developers can control and customize the request pipeline through middleware components.

  2. No Global.asax:

     • MVC.NET Core removes Global.asax. Instead, application startup and configuration are managed in Startup.cs with methods like ConfigureServices and Configure.

  3. Session and State Management:

     • Session management in MVC.NET is part of the page lifecycle.
     • In MVC.NET Core, session must be explicitly enabled as middleware and is not tied to the default pipeline.

  4. Routing:

     • MVC.NET uses RouteConfig to configure routes in Global.asax.
     • MVC.NET Core integrates routing as part of the middleware pipeline, managed in Startup.cs.

  5. Event Model:

     • MVC.NET relies heavily on event-driven programming.
     • MVC.NET Core uses the middleware model, which is simpler and more aligned with modern practices.

  Summary

  While both frameworks process requests and generate responses, MVC.NET Core introduces a streamlined, middleware-driven lifecycle that is more modern and modular than the traditional System.Web-based lifecycle in MVC.NET. This leads to better performance, flexibility, and control over how requests are handled and processed.

  I think it is fine I get in list format you mentioned page events only in ASP.NET Web form can I get the same format for other types of apps

  Classic ASP I think not event based, but others should have some pattern of event execution right can I get it

  Hi Sasi

  It was a good explanation

  But in that I need a few clarifications

  Architecture - MVC.NET    Vs MVC.NET Core
              MVC.NET also has same middleware that has the models right so what is the exact difference

  State Management - MVC.NET    Vs MVC.NET Core
                  You mentioned no viewstate if no state management there should be alternative state management right can you tell me what it is

  Also, you mentioned overall differences

  But can you find me what are the page events differences if it isn't matching each one in separate detail list of events or any diagrams I can get an idea of it

  1.Structure of MVC.NET Architecture

  MVC (Model-View-Controller) is a design pattern used in .NET applications to separate concerns:

  • Model: Represents the data and business logic. It handles data retrieval, storage, and validation.
  • View: The user interface that displays the data. Views are typically .cshtml files in ASP.NET MVC.
  • Controller: Manages the flow of the application. It handles user input, interacts with the model, and selects the view to render.

  2. Architecture of Web Apps in .NET Frameworks

  .NET offers several frameworks for building web applications:

  • ASP.NET Web Forms: Event-driven model with a page lifecycle. Suitable for rapid application development.
  • ASP.NET MVC: Follows the MVC pattern, providing better separation of concerns and testability.
  • ASP.NET Core: A cross-platform, modular framework that combines the best of ASP.NET MVC and Web API.
  • Blazor: Allows building interactive web UIs using C# instead of JavaScript. It can run on the server or client-side (WebAssembly).

  3. Page Lifecycle in ASP.NET Web Forms

  The ASP.NET Web Forms page lifecycle involves several stages:

  1. Page Request: A request is made for a page.
  2. Start: The page is initialized.
  3. Initialization: Controls on the page are initialized.
  4. Load: Page and controls load data.
  5. Postback Event Handling: Events are handled if it’s a postback.
  6. Rendering: The page is rendered into HTML.
  7. Unload: Cleanup activities occur.

  Comparison of Classic ASP, ASP.NET, MVC.NET, MVC.NET Core, and Blazor:
  Classic ASP

  • Type: Server-side scripting
  • Language: VBScript or JScript
  • Architecture: Monolithic
  • Features: Simple, lightweight, but limited in functionality and scalability.
  • Use Case: Suitable for small, simple web applications.

  ASP.NET

  • Type: Web framework
  • Language: C# or VB.NET
  • Architecture: Web Forms model (Event-driven)
  • Features: Rich server controls, state management, and event-driven programming.
  • Use Case: Good for enterprise-level applications but can be heavy.

  MVC.NET (ASP.NET MVC)

  • Type: Framework for building web applications
  • Language: C#
  • Architecture: MVC (Model-View-Controller)
  • Features: Separation of concerns, testability, and cleaner code organization.
  • Use Case: Ideal for applications requiring more control over HTML and URLs.

  MVC.NET Core

  • Type: Cross-platform web framework
  • Language: C#
  • Architecture: MVC (also supports Razor Pages)
  • Features: Lightweight, high performance, cross-platform, and modular.
  • Use Case: Best for modern web applications and services, especially cloud-based.
  • Blazor
  • Type: Framework for building interactive web UIs
  • Language: C#
  • Architecture: Can run on the server (Blazor Server) or client-side (Blazor WebAssembly)
  • Features: Allows C# to be used for both client and server-side code, rich UI components.
  • Use Case: Great for building SPAs (Single Page Applications) with a modern approach.

  Summary
  Classic ASP: Basic, older technology.
  ASP.NET: More powerful, suitable for large applications.
  MVC.NET: Focuses on structure and testability.
  MVC.NET Core: Modern, cross-platform, and high-performance.
  Blazor: Combines C# for both client and server, great for interactive apps.
