Syncfusion® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.

Register Syncfusion® Blazor Service

Interactive Render Mode Description
WebAssembly or Auto Open ~/_Imports.razor file from the client project.
Server Open ~/_import.razor file, which is located in the Components folder.

Import the Syncfusion.Blazor and Syncfusion.Blazor.Layouts namespace.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Layouts

Now, register the Syncfusion® Blazor Service in the ~/Program.cs file of the Blazor Web App.

If the Interactive Render Mode is set to WebAssembly or Auto, register the Syncfusion® Blazor service in both ~/Program.cs files (server and client projects) of the Blazor Web App.

...
...
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents()
    .AddInteractiveWebAssemblyComponents();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....
...
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.Services.AddSyncfusionBlazor();

await builder.Build().RunAsync();

If the Interactive Render Mode is set to Server, Register the Syncfusion® Blazor Service only in the server-side ~/Program.cs file.

...
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....

Add Stylesheet and Script Resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet reference in the <head> section and the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/material3.css" rel="stylesheet" />
</head>

<body>
    ....
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>

NOTE

Review the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in a Blazor application. Also, review the Adding Script Reference topic for different approaches to adding script references in a Blazor application.

Interactivity location RenderMode Code
Per page/component Auto @rendermode InteractiveAuto
  WebAssembly @rendermode InteractiveWebAssembly
  Server @rendermode InteractiveServer
  None —

NOTE

If an Interactivity Location is set to Global and the Render Mode is set to Auto or WebAssembly or Server, the render mode is configured in the App.razor file by default.

@* desired render mode define here *@
@rendermode InteractiveAuto
@using Syncfusion.Blazor.Layouts

<div style="height: 250px;">
    <SfTimeline>
        <TimelineItems>
            <TimelineItem></TimelineItem>
