Overview of this book

Today, full-stack development is the name of the game. Developers who can build complete solutions, including both backend and frontend products, are in great demand in the industry, hence being able to do so a desirable skill. However, embarking on the path to becoming a modern full-stack developer can be overwhelmingly difficult, so the key purpose of this book is to simplify and ease the process. This comprehensive guide will take you through the journey of becoming a full-stack developer in the realm of the web and .NET. It begins by implementing data-oriented RESTful APIs, leveraging ASP.NET Core and Entity Framework. Afterward, it describes the web development field, including its history and future horizons. Then, you’ll build webbased Single-Page Applications (SPAs) by learning about numerous popular technologies, namely TypeScript, Angular, React, and Vue. After that, you’ll learn about additional related concerns involving deployment, hosting, and monitoring by leveraging the cloud; specifically, Azure. By the end of this book, you’ll be able to build, deploy, and monitor cloud-based, data-oriented, RESTful APIs, as well as modern web apps, using the most popular frameworks and technologies.

The Startup class


The Startup class is initialized and executed right after the web application starts. It is located under the project root folder in the Startup.cs file. This is where the application services and request pipeline components can be configured.

The Startup class contains two methods:

  • ConfigureServices: This is where services will be added to the project. For example, this is where logging or authentication services are added.
  • Configure: This is where services and request pipeline components are configured. For example, the settings for the authentication and logging services will be set here.

Code execution order

The Startup class is executed only once during an application's lifespan, right after the web server has loaded the ASP.NET Core application.

The following screenshot shows the order of execution of the different methods in the classes involved in ASP.NET Core initialization:

Note

The Startup class is not the place to put any code other than initialization and configuration...
