Build modern web applications with C# from the browser to the database.
Blazor in Action with .NET 10 is a practical guide to building full stack Blazor applications with the latest .NET platform. It moves from core Razor components and render modes into data access, Web APIs, authentication, real time communication, AI integration, testing, performance, deployment, and scaling.
The book follows one hands on application, BlazorBistro, so each major Blazor concept connects to a real feature. You progress from a static server rendered menu to a full production application with persistent state, secured accounts, EF Core data access, SignalR updates, AI features, automated tests, observability, and cloud deployment.
Inside, you will learn how to:
- Understand the unified Blazor Web App model in .NET 10
- Work with Static SSR, Interactive Server, Interactive WebAssembly, and Interactive Auto render modes
- Build reusable Razor components with parameters, events, routing, layouts, forms, and validation
- Work with databases through Entity Framework Core
- Design and consume Minimal APIs and full stack HTTP services
- Implement authentication and authorization
- Build live interfaces with SignalR
- Manage state and persistence across different render modes
- Integrate JavaScript and browser features when needed
- Add AI features with Microsoft.Extensions.AI
- Test Blazor components and applications
- Improve rendering and WebAssembly performance
- Deploy and scale production Blazor applications with containers, Azure, health checks, structured logging, and OpenTelemetry
Instead of treating Blazor as an isolated front end framework, this book shows how render modes affect architecture, data access, state, security, performance, and deployment. You will see why server rendered components and WebAssembly components require different architectural choices, including when a component should access EF Core directly and when it should communicate through an API.
Whether you already work with C# or want to build production web applications without maintaining a separate JavaScript SPA stack, Blazor in Action with .NET 10 gives you a structured path from your first component to a deployed full stack application.
