    Study Notes

    Chapter 1 Introduction to Web Programming and ASP.NET Core MVC

    • Overview of Murach's ASP.NET Core MVC (2nd Edition)
    • Chapter 1: Introduces web programming and ASP.NET Core MVC.
    • Objectives (Part 1):
      • Describe web application components.
      • Detail the four components of a URL.
      • Distinguish between static/dynamic web pages, focusing on server roles (web, application, database).
      • Contrast internet and intranet.
      • Define HTTP request, response, and round trip.
      • Explain the Model-View-Controller (MVC) pattern.
      • Describe how MVC improves application development.
      • Introduce four ASP.NET app development models.
      • Differentiate between .NET Framework and .NET Core.
    • Objectives (Part 2):
      • Detail how ASP.NET Core apps configure middleware in the HTTP request/response pipeline.
      • Define and explain the concept of state in web applications.
      • Explain the differences between Visual Studio IDE and Visual Studio Code.
      • Describe how coding conventions benefit developers.

    Web Application Components

    • Diagram illustrates computer, tablet, smart phone connected to a web server via the internet.

    HTTP URL Components

    • Example URL: https://www.murach.com/shop-books/web-development-books/index.html
    • Components: Protocol, domain name, path, filename.

    Static Web Page Processing

    • Diagram shows a web browser requesting a static HTML page from a web server.
    • The web server responds with the requested HTML file.

    Simple HTTP Request and Response

    • Example HTTP GET request: GET / HTTP/1.1 Host: www.example.com
    • Example HTTP response headers: HTTP/1.1 200 OK Content-Type: text/html Content-Length: 136
    • Example HTTP response body (HTML).

    Web Application Protocols

    • HTTP (Hypertext Transfer Protocol): The foundation protocol for web communication.
    • HTTPS (Hypertext Transfer Protocol Secure): A secure version of HTTP.
    • TCP/IP (Transmission Control Protocol/Internet Protocol): Provides communication between two computers.

    Dynamic Web Page Processing

    • Diagram illustrates a web browser requesting a dynamic page.
    • The request goes through multiple servers (Web server, Application Server (ASP.NET Core), Database Server).

    MVC Pattern

    • Diagram displays the MVC pattern flow: HTTP Request -> Controller -> Model -> View -> HTTP Response.
    • Describes how the model, view, and controller components work together.

    MVC Pattern Components

    • The model handles data access and business logic.
    • The view displays data to the user.
    • The controller processes the request, retrieves data, and updates the view.

    MVC Benefits and Drawbacks

    • Benefits: Easier team work, automation, swapping components, maintainability.
    • Drawbacks: Increased setup effort.

    ASP.NET Web Forms

    • Released in 2002.
    • Enables Rapid Application Development (RAD).
    • Similarities to Windows Forms.
    • Drawbacks: Poor performance, inadequate separation of concerns, limited testing support, limited browser control.
    • Proprietary and Windows-only.

    ASP.NET MVC

    • Released in 2007.
    • Based on the MVC pattern.
    • Improved performance, separation of concerns, and testing support.
    • Uses the same ASP.NET Framework as Web Forms.

    ASP.NET Core MVC

    • Released in 2015.
    • Uses the MVC pattern in a more efficient way
    • Improvement on ASP.NET MVC in performance, modularity, and code cleanliness.
    • Open-source and runs on multiple platforms (Windows, macOS, Linux).

    ASP.NET Core Razor Pages

    • Provides the same features as ASP.NET Core MVC with a slightly different implementation approach
    • Uses a model built on top of MVC.

    .NET Framework vs. .NET Core

    • Comparison table illustrating difference in development environment and support.

    Middleware Pipeline

    • Diagram illustrates how a request travels across middleware.
    • Middleware functions in the pipeline: authentication, authorization, routing.
    • Illustration with request being short-circuited by middleware.
    • Middleware capabilities (generate responses, edit request/responses, short circuit requests).

    State in Web Apps

    • Web application state difficulty: HTTP is stateless; each request is treated independently and the application has no memory of previous interaction.
    • Explanation of state concepts: Property/variable/data maintained by application for one user.

    Visual Studio vs. Visual Studio Code

    • Comparison of Visual Studio IDE and Visual Studio Code for web development.

    Visual Studio Features

    • IntelliSense, automatic compilation, integrated debugger.
    • Runs on Windows and macOS

    Visual Studio Code Features

    • IntelliSense, automatic compilation, integrated debugger, runs everywhere.

    Folder and File Structure

    • Diagram illustrates common folders and files in an ASP.NET Core MVC web application.

    Naming Conventions

    • Guidance for naming controllers, models, and views in the app.
    • Suffixes for controllers.

    Product Model

    • Code listing for the Product model class.
    • Properties of the Product class (ProductID, Name, Price)

    ProductController Class

    • Code listing for the ProductController class
    • Includes methods (Detail, List)

    Product/Detail.cshtml View

    • Code listing for the Product/Detail.cshtml view.
    • Example layout elements (ID, Name, Price).

    Browser View

    • Screenshot of the Product/Detail/1 page displayed in a browser.

    Program.cs File

    • Code listing for the Program file outlining the middleware setup.

    Request URL Mapping

    • Table mapping different URLs to the corresponding controllers and actions.
