2.0 + 4 = 3.0??? .NET Framework confusion

I have had a few conversations recently about developers not looking at .NET Framework 3.0 as they believe it is a completely new version of the .NET Framework. Well that is not strictly true and perhaps the version of the framework has confused a few people.
The .NET Framework 3.0 combines the power of the .NET Framework 2.0 with four new technologies (2.0 + 4 technologies): Windows Presentation Foundation (WPF), Windows Communication Foundation (WCF), Windows Workflow Foundation (WF), and Windows CardSpace (WCS, formerly "InfoCard").
It should be noted that Microsoft Office SharePoint Server (MOSS) 2007 uses the Windows Workflow Foundation as part of .NET Framework 3.0 to drive the workflow capabilities used in Document Management and Web Content Management. MOSS provides a great example of what can be achieved using .NET 3.0 WF.
