Overview of this book

Blazor WebAssembly helps developers build web applications without the need for JavaScript, plugins, or add-ons. With its continued growth in popularity, getting started with Blazor now can open doors to new career paths and exciting projects – and Blazor WebAssembly by Example will make your first steps easier. This is a project-based guide that will teach you how to build single-page web applications with Blazor, focusing heavily on the practical over the theoretical by providing detailed step-by-step instructions for each project. The author also includes a video for each project showing her following the step-by-step instructions, so readers can use them if they're unsure about any particular step. In this updated edition, you'll start by building simple standalone web applications and gradually progress to developing more advanced hosted web applications with SQL Server backends. Each project will cover a different aspect of the Blazor WebAssembly ecosystem, such as Razor components, JavaScript interop, security, event handling, debugging on the client, application state, and dependency injection. The book’s projects get more challenging as you progress, but you don’t have to complete them in order, which makes this book a valuable resource for beginners as well as those who just want to dip into specific topics. By the end of this book, you will have experience and lots of know-how on how to build a wide variety of single-page web applications with .NET, Blazor WebAssembly, and C#.

Creating the Demo Blazor WebAssembly project

The Demo project that we are creating is based on one of the sample projects that are provided by the Blazor WebAssembly App project template. After we have used the template to create the project, we will examine the files in the sample project and update some of the files to demonstrate how to use Razor components. To elevate the development experience, we will enable Hot Reload. Finally, we will separate the code block of one of the components into a separate file to demonstrate how to use the code-behind technique to separate the markup from the code.

Creating the Demo project

Visual Studio comes with quite a few project templates. We are going to use the Blazor WebAssembly App project template to create our first Blazor WebAssembly project. Since this project template can be used to create many different types of Blazor projects, it is important to follow these instructions precisely:

  1. Open Microsoft Visual Studio 2022.
  2. Click the Create...
