A set of Blazor components wrapping Microsoft’s official Fluent UI Web Components. They implement the latest state of the Fluent design language, are built on FAST and work in every major browser.
The Microsoft.Fast.Components.FluentUI package provides a set of Blazor components which you can use to build applications that have
the look and feel or modern Microsoft applications. Some of the componets are wrappers around Microsoft's official FluentUI Web Components. Others are components
that leverage the Fluent UI design system or make it easier to work with Fluent UI. To get up and running with the library, see the 'Getting Started' section below.
The source for the library is hosted in the Fast Blazor repository at GitHub. Documentation on the components is available at the demo site and at docs.microsoft.com.
The source for @fluentui/web-components is hosted in the Fluent UI mono-repository. Documentation on the components is available on docs.microsoft.com.
The FluentUI Web Components are built on FAST and work in every major browser.
Upgrading from an earlier version
If you are upgrading from an earlier version of the library, please see the what's new for information on (breaking) changes.
Getting Started
To get started using the Fluent UI Blazor components for Blazor, you will first need to install the official Nuget package for Fluent UI in the project you would like to use the library and components. You can use the following command:
As of version 2.3 it is no longer needed to include the web-components script in your index.html or _Layout.cshtml file. The script is now included in
the library. This way we can safeguard that the you are always using the best matching version of the script.
If you are upgrading from an earlier version please remove the script from your index.html or _Layout.cshtml file.
Styles
In order for this library to work as expected, you will need to add the composed scoped CSS file for the components. This can be done by
adding the following line to the <head> section of your index.html or _Layout.cshtml file in the project you installed the package:
It is possible that the line is already in place (but commented out).
Reboot
Reboot is a collection of element-specific CSS changes in a single file to help kick-start building a site with the Fluent UI Blazor components for Blazor. It provides an elegant, consistent, and simple baseline to build upon.
If you want to use Reboot, you'll need to add to your index.html or _Layout.cshtml file a line that includes the stylesheet (.css file). This can be done by adding the following line to the <head> section:
It is entirely possible to build a site without using Reboot. If you choose not to use it, please do add the variables.css file (which is otherwise imported through the reboot.css file)
to your index.html or _Layout.cshtml file in the <head> section like this:
The file contains a number of CSS variables that are required to be defined for the components to work correctly.
Project file
if you want to use icons and/or emoji, starting with version 2.1 you need add a <PropertyGroup> to your project file. With this you can specify which icons and emoji are made available for usage and publication. Please refer to the project setup document for more information.
Code
Please refer to the code setup document to learn what needs to be included in your Program.cs file
so that all necessary services are available and setup in the correct way.
Getting started by using project templates
To make it easier to start a project that uses the Fluent UI Web Components for Blazor out of the box, we have created the
Microsoft.Fast.Templates.FluentUI template package.
The package contains templates for creating Blazor Server and/or Blazor WebAssembly apps that mimic the regular Blazor
templates with the Fluent UI components already set up (and all the Bootstrap styling removed). All components have been
replaced with Fluent UI counterparts (and a few extra have been added). Please see the documentation page
for more information.
If you want to use icons and/or emoji with applications based on the templates, you still need to make the changes to the project file
and Program.cs as described in the previous sections.
Using the FluentUI Web Components
With the package installed and the script configured, you can begin using the Fluent UI Blazor components in the same way
as any other Blazor component. Just be sure to add the following using statement to your views:
@using Microsoft.Fast.Components.FluentUI
Here's a small example of a FluentCard with a FluentButton that uses the Fluent "Accent" appearance:
You can add @using Microsoft.Fast.Components.FluentUI to the namespace collection in _Imports.razor, so you don't have to add it to every razor page that uses one of the components.
Configuring the Design System
The Fluent UI Blazor components are built on FAST's Adaptive UI technology, which enables design customization and personalization, while automatically
maintaining accessibility. This is accomplished through setting various "Design Tokens". The library exposes all of the (over 160) Design Tokens, which you can use both from code as in a declarative way in your .razor pages. The three different ways of working with design tokens are described in the design tokens page.
Blazor Hybrid
Starting with the 2.0 release, you can also use this library in your Blazor Hybrid projects. Setup is almost the same as described in the "Getting started" section above, but to get everything to work you'll need to take two extra steps:
You need to add a MAUI specific IStaticAssetService implementation.
Due to some issues, this file can't be part of the library (yet) so this needs to be added manually to your MAUI Blazor project.
Create a new class in you project called FileBasedStaticAssetService.cs Replace it's contents with the following:
using System.Net;
using Microsoft.Fast.Components.FluentUI.Infrastructure;
namespace Microsoft.Fast.Components.FluentUI;
public class FileBasedStaticAssetService : IStaticAssetService
{
public async Task<string> GetAsync(string assetUrl, bool useCache = false)
{
string result = null;
HttpRequestMessage message = CreateMessage(assetUrl);
if (string.IsNullOrEmpty(result))
{
result = await ReadData(assetUrl);
}
return result;
}
private static HttpRequestMessage CreateMessage(string url) => new(HttpMethod.Get, url);
private static async Task<string> ReadData(string file)
{
using var stream = await FileSystem.OpenAppPackageFileAsync($"wwwroot/{file}");
using var reader = new StreamReader(stream);
return await reader.ReadToEndAsync();
}
}
You need to make some changes in your MauiProgram.cs file
Make sure the following is added before the return builder.Build() line:
If you want to use the <FluentDataGrid> with data provided through EF Core, you need to install
an additional package so the grid knows how to resolve queries asynchronously for efficiency. .
