Overview of this book

Blazor WebAssembly is a revolutionary technology in software development that enables you to develop web applications with a rich user interface using C# without JavaScript. It can be run natively in the browser and soon on mobile apps with .NET MAUI, making it a superweapon in the .NET developer’s toolbox. This capability has opened the doors for the JavaScript community to have a stable framework to build single page applications (SPAs) maintained by Microsoft and driven by the community. Mastering Blazor WebAssembly is a complete resource that teaches you everything you need to build client-side web applications using C# & .NET 7.0. Throughout this book, you’ll discover the anatomy of a Blazor WebAssembly project, along with the build, style, and structure of the components. You’ll implement forms to catch user input and collect data, as well as explore the topics of navigating between the pages in depth. The chapters will guide you through handling complex scenarios like RenderTrees, writing efficient unit tests, using variant security methods, and publishing the app to different providers, all in a practical manner. By the end of this book, you’ll have the skills necessary to build web apps with Blazor WebAssembly, along with the basics for a future in mobile development with .NET MAUI and Blazor.

  • Global styles
  • Isolated styles (scoped)
  • Inline styles

Isolated styles

Blazor provides us with a powerful way to style our components by keeping the styles separated from each other. This means small, clean styles, scoped for each component.

To reference the isolated styles, you need to add a link tag with a reference using the syntax {AssemblyName}.styles.css.

Let’s get started using isolated styles to style our BookCard component:

  1. Create a CSS file in the same folder of the BookCard component following the convention {ComponentName}.razor.css – in our case, BookCard.razor.css. This will make Visual...
