The Syncfusion.EJ2.AspNet.Core NuGet package has dependencies, Newtonsoft.Json for JSON serialization and Syncfusion.Licensing for validating Syncfusion license key.
Add Syncfusion ASP.NET Core Tag Helper
Open ~/Pages/_ViewImports.cshtml
file and import the Syncfusion.EJ2
TagHelper.
@addTagHelper *, Syncfusion.EJ2
Add script resources
Here, script is referred using CDN inside the <head>
of ~/Pages/Shared/_Layout.cshtml
file as follows,
<head>
...
<!-- Syncfusion ASP.NET Core controls scripts -->
<script src="https://cdn.syncfusion.com/ej2/27.2.2/dist/ej2.min.js"></script>
</head>
NOTE

Register Syncfusion Script Manager
Also, register the script manager <ejs-script>
at the end of <body>

<body>
...
<!-- Syncfusion ASP.NET Core Script Manager -->
<ejs-scripts></ejs-scripts>
</body>

List<DefaultBulletData> bulletData = new List<DefaultBulletData>
{
new DefaultBulletData { value = 270, target = 250}
};
}
<ejs-bulletchart id="bulletgraph" minimum="0" maximum="300" interval="50" valueField="value" targetField="target" dataSource="bulletData">
</ejs-bulletchart>
public class DefaultBulletData
{
public double value;
public double target;
}
