Mastering Blazor with Visual Studio 2026 is a practical, step-by-step guide for students, self-learners, educators, and developers who want to build modern interactive web applications using C#, Razor components, Visual Studio 2026, and .NET 10.
Blazor enables .NET developers to create rich web applications while using C# for much of the application logic. Instead of learning concepts only in isolation, this book takes a hands-on approach, showing you how Blazor applications are created, structured, tested, and developed into complete real-world projects.
The book begins with the fundamentals of Blazor and gradually progresses to reusable components, routing, layouts, event handling, data binding, forms, validation, state management, dependency injection, collections, Web APIs, and CRUD applications. You will then explore Blazor Server, Blazor WebAssembly, authentication and authorization, JavaScript interop, file uploads, charts, rich user interfaces, debugging, testing, performance optimization, and deployment.
To make learning easier, the book includes numerous screenshots and practical code examples, allowing you to follow the development process visually in Visual Studio 2026. GitHub source code is also provided for every chapter, so you can download, run, study, and modify the completed examples yourself.
Inside this book, you will learn how to:

• Create and structure Blazor projects in Visual Studio 2026
  
• Build reusable Razor components
  
• Work with layouts, routing, and navigation
  
• Handle events and interactive user interfaces
  
• Use one-way and two-way data binding
  
• Build forms with validation and user feedback
  
• Manage component and application state
  
• Use dependency injection and service classes
  
• Display, search, filter, and sort collections of data
  
• Call ASP.NET Core Web APIs with HttpClient
  
• Build complete CRUD applications
  
• Understand Blazor Server and Blazor WebAssembly
  
• Implement authentication and authorization
  
• Use JavaScript interop for browser functionality
  
• Work with file uploads, charts, notifications, and modal dialogs
  
• Debug and test Blazor applications
  
• Improve application performance
  
• Build a complete Student Management Portal capstone project
  
• Prepare and publish Blazor applications for deployment
  

The final capstone project brings the major concepts together in a Student Management Portal featuring a dashboard, student management, search and filtering, CRUD operations, validation, file uploads, charts, protected pages, and a structured service-based architecture. This reflects the book's progression from individual Blazor concepts to a complete application.
Whether you are learning Blazor for the first time, moving from desktop development to the web, expanding your C# skills, or modernizing your ASP.NET knowledge, Mastering Blazor with Visual Studio 2026 provides a clear, practical, and project-based path to building modern .NET web applications.
Learn by building, follow the examples with screenshots, and use the complete GitHub source code to turn Blazor concepts into working applications.
