Overview of this book

Blazor WebAssembly allows you to build web apps without the need for JavaScript, plugins, or add-ons. With its continued growth in popularity, Blazor WebAssembly can open doors to new career paths and exciting projects, and Blazor WebAssembly by Example makes getting started easy. This project-based guide teaches you how to build single-page web applications by focusing heavily on the practical over the theoretical. The author provides step-by-step instructions for each project as well as a video of her following those exact steps. In this updated edition, we've added two new chapters on integrating artificial intelligence into web apps built with Blazor WebAssembly. You'll start with simple standalone web apps and gradually progress to hosted web applications with SQL Server backends. Each project covers a different concept from the Blazor WebAssembly ecosystem, such as Razor components, JavaScript interop, security, events, debugging, state management, hosted applications, REST APIs, and AI. 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'll be building your own web apps with .NET and C# using Blazor WebAssembly.

You can use Hot Reload with or without the debugger. In Visual Studio 2026, Hot Reload is enabled by default.

This is the Hot Reload drop-down button that is accessed from the toolbar:

Hot Reload is supported for most changes to a component, including stylesheets. However, sometimes a change will require that the application be restarted.

This is a list of a few activities that require a restart:
