Reporting on Business Objects with C#3.0 and ReportViewer

Most of you remember that ReportViewer is a real pain when it comes to working with business objects.

I totally agree with that. In the past it has been a pain as you either had to use the Subreport (which is not well supported)
or List approach (which would involve to create a joined view of data first) which were both not very handy.

Now with the new LINQ Features of C#3.0 you can much easier report against business objects (once they support linq - as TA4.0SP1 does).
