Microsoft Fluent UI Blazor is a component library that provides Razor components for building Blazor applications with the Fluent Design System.
The library solves the problem of implementing modern Microsoft-style user interfaces in ASP.NET Core Blazor projects. It wraps Microsoft's official Fluent UI Web Components and provides additional components that leverage the Fluent Design System, allowing developers to build applications with a consistent, contemporary look and feel without designing components from scratch.
The tool targets developers building Blazor applications on .NET 8 and 9 who want to adopt Microsoft's design language. It suits projects ranging from simple web applications to more complex scenarios like .NET Aspire starter applications and MAUI Blazor hybrid applications. The library offers multiple entry points: developers can use pre-configured dotnet templates that come with design and components already set up, or manually install the NuGet package into existing projects. The templates include options for standalone WebAssembly projects, Aspire starter applications, and MAUI Blazor hybrid and web applications.
The project maintains active engagement with users through a clear issue reporting process that requires ready-to-run reproduction code, closing issues without sufficient detail after a set period. Development activity shows consistent attention to version compatibility, with explicit guidance for users on older .NET versions to use earlier package versions. The library documentation is centralized on a dedicated demo site with a backup site available, indicating infrastructure investment in accessibility and reliability.
