Alternatively, you can utilize the following package manager command to achieve the same.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Calendars

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

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