A report can be bound to a business object registered from code before it is shown or designed.

Register the object.
Report = new StiReport();
Report.Load(await Http.GetByteArrayAsync("Reports/BusinessObjects.mrt"));

var list = GetBusinessObject();
Report.RegBusinessObject("MyList", list);
Report.Dictionary.Synchronize();

How it works. The report renders directly from the registered object, so your domain classes drive the output with no dataset conversion.
