Overview of this book

Web Development with Blazor is your essential guide to building and deploying interactive web applications in C# – without relying on JavaScript. Written by an early Blazor adopter and updated for .NET 8, this book takes you through the end-to-end development of an example app, helping you to overcome common challenges along the way. You’ll pick up both Blazor Server and Blazor WebAssembly and discover cutting-edge tools to enrich your development experience. Responding to evolving needs, this edition introduces flexible hosting models, allowing you to mix and match hosting approaches to create flexible and scalable Blazor applications. It also presents the new Blazor templates, which provide ready-made solutions to simplify and expedite development. You'll learn about the game-changing server-side rendering (SSR), a hybrid hosting model blending the strengths of Blazor Server and Blazor WebAssembly, as well as streaming rendering, a new technique that boosts the performance and user experience of Blazor apps. By the end of this book, you'll have the confidence you need to create and deploy production-ready Blazor applications using best practices, along with a big-picture view of the Blazor landscape.

There are a bunch of DataAnnotations instances in .NET already that we can use; we can also build our own annotations.

  • Required: This makes the field required.
  • Email: This will check that the entered value is an email address.
  • MinLength: This will check that the number of characters is not fewer than the value specified.
  • MaxLength: This will check that the number of characters is not exceeded.
  • Range: This will check that the value is within a specific...
