Blazor
Blazor is a free, open-source web framework developed by Microsoft that allows developers to build interactive web user interfaces (UIs) using C# and .NET instead of JavaScript. It enables full-stack web development with .NET by running C# code directly in the browser via WebAssembly (Blazor WebAssembly) or on the server with real-time UI updates (Blazor Server). This framework integrates with the .NET ecosystem, providing a component-based architecture similar to modern JavaScript frameworks like React or Angular.
Developers should learn Blazor when building web applications where they want to leverage existing .NET skills, share code between client and server, or avoid JavaScript for UI logic. It is particularly useful for enterprise applications, internal tools, or projects requiring strong type safety and .NET libraries, as it allows full-stack development with a single language (C#) and framework (.NET). Use cases include data-driven dashboards, line-of-business apps, and scenarios where WebAssembly performance or server-side rendering is beneficial.
