I have build an application in VIsual Web Developer 2008 Express which uses the Report Viewer 2008 Service Pack 1 (build under .net 2.0).
I have recently updated to Visual Studio 2010 Ultimate and the report pages no longer work. I get - The type or namespace 'Reporting' doesn not exist in the namespace 'Microsoft' (are you missing an assembly reference?)
It will work fine if I cange the target framework to 3.5 but I want to keep it at 2.0 for now.
