Why can't I see Microsoft.ReportViewer.WebForms version 10.0.0.0 in "Add Reference..." dialog?

Question

I have a VS2008 Reporting Services project (database: SQL Server 2008 RC2). This project has been updated from VS2005/SQL2005.

I need to update the Report Viewer control to version 10.0.0.0. But when I install the Redistributable (http://www.microsoft.com/downloads/en/details.aspx?displaylang=en&FamilyID=a941c6b2-64dd-4d03-9ca7-4017a0d164fd), it isn't added to the .NET-tab in the 'Add reference...' dialog!

I can see the Microsoft.ReportViewer 8.0.0.0 and Microsoft.ReportViewer 9.0.0.0 in the dialog, but no 10.0.0.0

I tried running uninstalls for everything ReportViewer related, and reinstalling the ReportViewer 10.0.0.0 control. But I still see both version 8 and 9 in the dialog, but no version 10!

Checking the GAC through Start->Run->Assembly I can see all three versions. I cannot remove 8 and 9 because they apparently are used by other programs...

This is driving me somewhat nuts...

What do I have to do to make this assembly available in the "Add Reference..." dialog in Visual Studio 2008??

OK, found a solution: Apparently VS2008 combined with ReportViewer2010 requires a little handy-work:

After I extracted the assembly DLLs from the GAC, I could add them to the 'Add reference...' dialog as described here:

I hope this'll help another distressed soul! ;)
