To add ASP.NET Core controls in the application, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search for Syncfusion.EJ2.AspNet.Core and then install it. Alternatively, you can utilize the following package manager command to achieve the same.

Open ~/Pages/_ViewImports.cshtml file and import the Syncfusion.EJ2 TagHelper.
@addTagHelper *, Syncfusion.EJ2Add stylesheet and script resources
Here, the theme and script is referred using CDN inside the <head> of ~/Pages/Shared/_Layout.cshtml file as follows,
<head>
...
<!-- Syncfusion ASP.NET Core controls styles -->
<link rel="stylesheet" href="https://cdn.syncfusion.com/ej2/28.1.33/fluent.css" />
