This document discusses Blazor, a framework that allows web developers to build client-side web applications using C# instead of JavaScript. It provides a high-level overview of key Blazor concepts: - Blazor applications compile C#/Razor code to WebAssembly using .NET, allowing developers to write client-side web apps with C# instead of JavaScript. - It supports common features like components, routing, dependency injection and lifecycle methods that developers expect from a modern web framework. - Developers can write code in C# and Razor and Blazor will handle rendering the UI and responding to user input without needing to write any JavaScript code.
