First, you need to add the StiNetCoreViewer component to the view page: 
@using Stimulsoft.Report.Web;
@using Stimulsoft.Report.Mvc;

...

@Html.StiNetCoreViewer(new StiNetCoreViewerOptions()
{
    Actions =
    {
        GetReport = "GetReport",
        ViewerEvent = "ViewerEvent"
    }
})

In the options above we define several actions, and we need to add it in the controller.

The GetReport() action loads the report template and data, after thet it returns answer to the client part of the viewer using the GetReportResult() static method: 
public IActionResult GetReport()
 {
	// Loading the report template
	var reportPath = StiNetCoreHelper.MapPath(this, "Reports/TwoSimpleLists.mrt");
	var report = new StiReport();
	report.Load(reportPath);

	// Deleting connections in the report template
	report.Dictionary.Databases.Clear();

	// Loading data from the XML file
	var dataPath = StiNetCoreHelper.MapPath(this, "Reports/Data/Demo.xml");
	var data = new DataSet();
	data.ReadXml(dataPath);

	// Registering data in the report
	report.RegData(data);
	
	// Syncing the data structure, if required
	//report.Dictionary.Synchronize();

	return StiNetCoreViewer.GetReportResult(this, report);
}

Now, let's try with Designer: 
@using Stimulsoft.Report.Mvc;

...

@Html.StiNetCoreDesigner(new StiNetCoreDesignerOptions()
{
	Actions =
	{
		GetReport = "GetReport",
		PreviewReport = "PreviewReport",
		DesignerEvent = "DesignerEvent"
    }
})

You can use PreviewReport() method to load data: 
 public IActionResult PreviewReport()
{
	// Getting a preview report
	var report = StiNetCoreDesigner.GetActionReportObject(this);

	// Deleting connections in the report template
	report.Dictionary.Databases.Clear();

	// Loading data from the XML file
	var dataPath = StiNetCoreHelper.MapPath(this, "Reports/Data/Demo.xml");
	var data = new DataSet();
	data.ReadXml(dataPath);

	// Registering data in the report
	report.RegData(data);

	// Syncing the data structure, if required
	//report.Dictionary.Synchronize();

	return StiNetCoreDesigner.PreviewReportResult(this, report);
