Prerequisites

You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion® Blazor Extension.
You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.
Install Syncfusion® Blazor Buttons and Themes NuGet in the Blazor Web App
To add Blazor Floating Action Button component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.Buttons and Syncfusion.Blazor.Themes.
If you utilize WebAssembly or Auto render modes in the Blazor Web App need to be install Syncfusion® Blazor components NuGet packages within the client project.
Alternatively, you can utilize the following package manager command to achieve the same.
Install-Package Syncfusion.Blazor.Buttons -Version 28.1.33
Install-Package Syncfusion.Blazor.Themes -Version 28.1.33NOTE
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
Open ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.Buttons namespace.
@using Syncfusion.Blazor
@using Syncfusion.Blazor.ButtonsNow, register the Syncfusion® Blazor Service in the ~/Program.cs file of your Blazor Web App. For a app with WebAssembly or Auto (Server and WebAssembly) interactive render mode, register the Syncfusion® Blazor service in both ~/Program.cs files of your web app.
....
using Syncfusion.Blazor;
....
builder.Services.AddSyncfusionBlazor();
....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/bootstrap5.css" rel="stylesheet" />
</head>

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