In plain English

This library provides ready-made user interface components for building web applications with Blazor, Microsoft's framework for writing web apps in C# instead of JavaScript. The components follow Microsoft's Fluent Design System, which means they look and behave like modern Microsoft applications such as those in Microsoft 365. Developers can drop these components into a Blazor project to get buttons, dialogs, data grids, navigation menus, and other common interface elements without building them from scratch. Some components wrap Microsoft's existing Fluent UI Web Components, while others are designed specifically to fit Blazor's way of working. The easiest way to start is with the provided project templates. Running a single command creates a new project that already has the design and components wired up. Alternatively, developers can add the library as a standard package to an existing project. Optional add-on packages provide a large set of icons and emoji if needed. The library targets .NET 8 and 9. Older versions of .NET are not supported in the current release. A live demo site lets anyone browse all available components and try them interactively before using them in a project. Documentation lives on the same site. The project is maintained by Microsoft and is available under the MIT license.
