Study Notes
Chapter 1: Introduction to Web Programming and ASP.NET Core MVC
- This chapter introduces web programming and ASP.NET Core MVC.
- Objectives covered include describing web app components, URL components, static/dynamic web pages, the internet/intranet, HTTP requests/responses/round trips, the MVC pattern, and ASP.NET app development models.
- Also differentiating between .NET Framework and .NET Core is covered.
Objectives (Part 1)
- Web application components are described.
- The four components of a URL (protocol, domain name, path, filename) are detailed.
- Static and dynamic web pages, focusing on the roles of web servers, application servers, and database servers, are differentiated.
- The differences between the internet and intranet are outlined.
- Terms including HTTP request, HTTP response, and round trip are defined.
- The MVC pattern's model, view, and controller components are described.
- The benefits of using the MVC pattern for application development are explained.
- Four programming models used for ASP.NET applications are identified.
- The distinction between .NET Framework and .NET Core is made.
Objectives (Part 2)
- How ASP.NET Core apps configure middleware in the HTTP request and response pipeline is discussed.
- The concept of state in web applications and why tracking it can be challenging is explained, along with the impact as well.
- Visual Studio IDE and Visual Studio Code (VS Code) code editor functionalities are differentiated.
- How coding conventions improve development is explained.
Components of a Web App
- A diagram illustrates how a computer, tablet, and smartphone interact with a web server through the internet.
Components of an HTTP URL
- An example URL (https://www.murach.com/shop-books/web-development-books/index.html) is used to illustrate the protocol, domain name, path, and filename.
How a Web Server Processes a Static Web Page
- A diagram depicts the interaction between a web browser and a web server, highlighting the HTTP request and response with HTML, CSS, and Javascript.
A Simple HTTP Request/Response
- A sample HTTP request and response are shown, including the protocol, status code, content type, and content length. An example of HTML content is also provided.
Three Protocols Web Apps Depend On
- HTTP (Hypertext Transfer Protocol), HTTPS (Hypertext Transfer Protocol Secure) and TCP/IP (Transmission Control Protocol/Internet Protocol) are mentioned as crucial protocols.
How a Web Server Processes a Dynamic Web Page
- A diagram shows the involvement of a web server, application server (ASP.NET Core), and database server (SQL Server) in processing dynamic web pages.
The MVC Pattern
- A diagram depicts the interaction of web browsers, controllers, models, views, and database servers in an MVC application.
Components of the MVC Pattern
- Descriptions for the model, view, and controller components of MVC are provided.
Benefits of the MVC Pattern
- The pattern's benefits, including improved teamwork and maintainability, are listed. Automatic testing is also mentioned as a benefit.
Drawbacks of the MVC Pattern
- The downside of MVC is that it requires extra effort to set up.
ASP.NET Web Forms
- Web Forms was released in 2002.
- It uses a rapid application development (RAD) design surface similar to Windows Forms.
- Associated problems with web forms include performance problems, inadequate separation of concerns, limitations with automated testing and limited control over HTML/CSS/JavaScript. It's also proprietary and limited to Windows.
ASP.NET MVC
- MVC was released in 2007.
- It fixes many perceived problems with web forms which resulted on better performance and support for automated testing.
- Also uses the same ASP.NET Framework as Web Forms.
ASP.NET Core MVC
- Core MVC was released in 2015.
- It leverages an MVC pattern for web development.
- It improves on previous versions with better performance and modular code. The open-source framework runs on multiple platforms, including Windows, macOS, and Linux.
ASP.NET Core Razor Pages
- A Razor Pages component provides the same functionalities as ASP.NET Core MVC but uses a different model structure.
Some components of .NET Framework and .NET Core
- Shows the relationships, differences, and operating systems supporting .NET Framework and .NET Core.
A Request that Makes it Through all Middleware
- A request goes through authentication, authorization, and routing middleware.
- Each stage of the request is shown in the pipeline flow.
A Request that's Short-circuited by Middleware
- A request reaches a stage in the pipeline where its flow is diverted and finishes processing without additional middleware components.
Middleware
- Middleware has the capability of creating, altering, or even terminating requests and responses.
Why State is Difficult to Track in a Web App
- A diagram illustrating how web requests operate and why it is hard to track web application state.
State Concepts
- State is defined as the current status of application data specific to a user, and HTTP is a stateless protocol.
Visual Studio with an ASP.NET Core MVC App/ Visual Studio Code with an ASP.NET Core MVC app
- Screen captures illustrating Visual Studio and Visual Studio Code development environments.
Features of Visual Studio/ Visual Studio Code
- Features of these development environments are noted. (IntelliSense, automatic compilation, integrated debugging, platform compatibility).
Some of the Folders and Files for a Web App
- Structure of common folders and files found in a typical web application. Examples are shown. (Controllers, Models, Views, wwwroot, Program.cs).
Some Naming Conventions for ASP.NET Core MVC
- Guidelines for the organization of files and folders relating to MVC applications.
The Code for a Model Class Named Product
- Example code for a Product model class.
The Code for the ProductController Class
- Example code for a ProductController class.
The Code for the Product/Detail.cshtml View
- Example code for the view used for displaying Product details.
The View Displayed in a Browser
- Example of a browser view displaying product details. Example URL and title are shown.
The Program.cs File
- Code snippet illustrating a Program.cs file and configuring the HTTP request pipeline, including default HSTS configurations.
How Request URLs Map to Controllers and Actions by Default
- Explanation of how different URLs map to controllers and actions in an ASP.NET Core MVC application that is configured with the program.cs file shown. Examples are shown.
