I'm implementing a reporting feature in a .net core application. This feature was previously implementing in a webforms application. The logic to produce a Telerik.Reporting.Report object exists already. In the webforms application you could provide the report source to the report viewer like:
ReportViewer.ReportSource = new Telerik.Reporting.InstanceReportSource { ReportDocument = ReportObject };
In the .net core application I have managed to setup the HTML5 report viewer and displayed the example report. I'm am struggling to find any documentation or examples on how to use a Telerik.Reporting.Report object as the source for the HTML5 report viewer. Is it possible to dynamically generate a Telerik.Reporting.Report and use that as the report viewer report source?

HTML5 Report Viewer uses Reporting REST service to get the reports which are actually processed on the server. It is a client-server model, in which the client(viewer) sends short string descriptions (messages) to the server and gets the content from the server.
The viewer can send a description of the report (its assembly qualified name passed with TypeReportSource) or path to a report file (passed with UriReportSource), where the string description is interpreted by the service's report resolver which returns a ReportSource object.
Complex objects such as report instance (InstanceReportSource) cannot be transferred in a message. Therefore, it will require a custom report resolver where the report instance can be modified in resolver's Resolve() method and returned as InstanceReportSource.
More detailed information can be found in How to display a report via InstanceReportSource in the HTML5 Viewer KB article.
