You have answered your own question, 3.0 = same framework as 2.0 + WCF + WPF + WF.

.NET Framework 2.0

• A new hosting API for native applications wishing to host an instance of the .NET runtime
• Full 64-bit support for both the x64 and the IA64 hardware platforms.
• Language support for Generics built directly into the .NET CLR.
• Many additional and improved ASP.NET web controls.
• New data controls with declarative data binding.
• New personalization features for ASP.NET, such as support for themes, skins and webparts.

.NET Framework 3.0

• Windows Presentation Foundation (WPF), formerly code-named Avalon; a new user interface subsystem and API based on XML and vector graphics, which will make use of 3D computer graphics hardware and Direct3D technologies.
• Windows Communication Foundation (WCF), formerly code-named Indigo; a service-oriented messaging system which allows programs to interoperate locally or remotely similar to web services.
• Windows Workflow Foundation (WWF) allows for building of task automation and integrated transactions using workflows.
• Windows CardSpace (WCS), formerly code-named InfoCard; a software component which securely stores a person's digital identities and provides a unified interface for choosing the identity for a particular transaction, such as logging in to a website.

2.0 => framework that shipped with VS 2005 VB 8.0 / C# 2.0
3.0 => same framework as 2.0 + WCF + WPF + WF

2.0 and 3.0 both use the 2.0 CLR (common language runtime). The only difference is addition of Windows Communication Foundation, Windows Presentation Foundation, and Workflow components in 3.0.
