Method not found: 'Void CrystalDecisions.Shared.ReportStateInfo.set_DataSou


We have a VB.NET project which has recently been migrated from Visual Studio 2003 / .NET 1.1 and Crystal Reports 11 to Visual Studio 2010 / .NET 3.5 and Crystal Reports 2008.

One of the forms uses the control, and at the point of trying to display a report, pops up the following error since the migration:

Method not found: 'Void CrystalDecisions.Shared.ReportStateInfo.set_DataSource(System.Data.DataSet)'.

All other Crystal Reports functionality is working fine. As far as I can see, the control being used is version 12.0.2000.0 (although 12.0.1100.0 also seems to be available, and suffers from the same problem). All of the Crystal Reports references in the project point to files in C:\Program Files\Business Objects\Common\4.0\managed and are version 12.0.1100.0.

Has anyone else encountered this problem? Are the wrong versions of the control / DLLs being used? Any advice on how to get this working would be useful!

Thanks in advance,
