I have a 2008 MS Datacenter server with Visual Studio 2008 and Crystal Reports 2008.
When I "Add" a Crystal Reports to the Visual Studio solution, nothing works. The "Document" is blank (Grey) and the Document Outline is also blank. No amount of clicking, dragging or otherwise has any effect.
This is also true of reports created using the Crystal Reports 2008 software that is added to the solution. Same with reports created on VS 2005 that are upgraded.
In essence, it ain't working.
