Take advantage of your C# skills to build UI components and client-side experiences with .NET. With this practical guide, you'll learn how to use Blazor WebAssembly to develop next-generation web experiences. Built on top of ASP.NET Core, Blazor represents the future of .NET single-page application investments.

Author David Pine, who focuses on .NET and Azure content development at Microsoft, explains how WebAssembly enables many non-JavaScript-based programming languages to run on the client browser. In this book, you'll learn about real-time web functionality with ASP.NET Core SignalR and discover strategies for bidirectional JavaScript interop. David also covers component data binding, hierarchical event-driven communications, in-memory state management, and local storage.

This book shows you how to:

Create a beautiful, feature-rich Blazor app
Develop and localize an enterprise-scale app using GitHub Actions and Azure Cognitive Services Translator
Create advanced validation scenarios for input-based components with forms
Automatically deploy and host to Azure Static Web Apps, and rely on HTTP services
Use a geolocation service and speech synthesis and recognition native to the browser
Author a custom modal verification mechanism for validating a user
