Introducing Syncfusion Toolkit for Blazor: Free Open-Source Blazor Components

What is Syncfusion Toolkit for Blazor?

The Syncfusion^® Toolkit for Blazor is a free, MIT-licensed collection of open-source Blazor UI components designed to help developers build modern Blazor applications faster.

Hosted on GitHub and distributed through NuGet, the toolkit provides reusable, customizable, and production-friendly UI components that developers can easily integrate into their applications.

Instead of building common UI infrastructure from scratch, developers can use ready-to-integrate components for charts, forms, dialogs, uploads, date selection, input handling, and other common application scenarios.

The Toolkit for Blazor focuses on providing essential UI building blocks that help developers quickly create modern business applications with cleaner and more maintainable code.

Why we built Syncfusion Toolkit for Blazor

Syncfusion has long provided a comprehensive commercial suite of Blazor UI components for enterprise application development. With the Syncfusion Toolkit for Blazor, we are extending our support for the Blazor developer community by offering a free and open-source set of essential UI components.

Open source helps developers by providing:

• Greater transparency,
• More flexibility,
• Easier customization,
• Community-driven collaboration, and
• Long-term control over application UI infrastructure.

Our goal is simple:

Help developers build modern Blazor applications faster using reusable, community-friendly UI components under the MIT license.

This release reflects our continued commitment to supporting the .NET and Blazor ecosystem through open-source contributions and developer-focused tooling.

Getting started with Syncfusion Toolkit for Blazor

Let’s create a simple Blazor app and add your first component from the Toolkit for Blazor.

Step 1: Create a new Blazor Web app

Start by creating a new Blazor Web app project using the following command.

dotnet new blazor -n MyBlazorApp

cd MyBlazorApp

Step 2: Install the NuGet package

Install the Syncfusion Toolkit for Blazor package using the following command:

dotnet add package Syncfusion.Blazor.Toolkit

Step 3: Register Syncfusion services

In your Program.cs file, register the Syncfusion Blazor service.

using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

builder.Services
       .AddRazorComponents()
       .AddInteractiveWebAssemblyComponents();

builder.Services.AddSyncfusionBlazor();

var app = builder.Build();

// Remaining app configuration

Step 4: Import the required namespaces

Add the following namespaces to the _Imports.razor file.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Toolkit

Step 5: Add the stylesheet reference

Add the required CSS reference to your layout file.

<link href="_content/Syncfusion.Blazor.Toolkit/styles/fluent2.min.css" rel="stylesheet" />

Step 6: Add your first component

Now, you can use the Toolkit for Blazor components on your Blazor page.

@page "/"
@using Syncfusion.Blazor.Toolkit.Buttons

<h1>Welcome to Syncfusion Toolkit for Blazor!</h1>

<SfButton OnClick="@HandleButtonClick" CssClass="e-success">
    Click Me!
</SfButton>

<p>Button clicked: <strong>@clickCount</strong> times</p>

@code
{
    private int clickCount = 0;

    private void HandleButtonClick()
    {
        clickCount++;
    }
}

Step 7: Run the application

Launch your application using the following command:

dotnet run

And, open the application in your browser and see the Syncfusion Toolkit for Blazor components in action.
