Register Syncfusion® Blazor Service

Open ~/_Imports.razor and import the Syncfusion.Blazor and Syncfusion.Blazor.Inputs namespaces.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Inputs

Now, register the Syncfusion® Blazor service in the ~/Program.cs file of your Blazor WebAssembly app.

using Microsoft.AspNetCore.Components.Web;
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");
builder.RootComponents.Add<HeadOutlet>("head::after");

builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

builder.Services.AddSyncfusionBlazor();
await builder.Build().RunAsync();
....

Add stylesheet and script resources

The theme stylesheet and script are provided via NuGet as Static Web Assets. Include the stylesheet and script references in the <head> section of the ~/index.html file.

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</head>

NOTE

See Blazor Themes for different theme options (such as Bootstrap 5, Fluent, or Material) and referencing methods (Static Web Assets, CDN, and CRG). For script reference approaches, see Adding script references.
