Microsoft .NET Framework 3.0 = .NET 2.0 + Windows Communication Foundation + Windows Presentation Foundation + Windows Workflow Foundation + Windows Card Space.

Yes, Now we are into Microsoft .NET Framework 3.0 which is nothing but Microsoft .NET Framework .NET 2.0 + Windows Communication Foundation + Windows Presentation Foundation + Windows Workflow Foundation + Windows Card Space.

Microsoft ASP.NET 2.0 includes a number of services that store state in databases and other storage media. For example, the session state service manages per-user session state by storing it in-process, in memory in an external process , or in a Microsoft SQL Server database, whereas the membership service stores user names, passwords, and other membership data in Microsoft SQL Server or Microsoft Active Directory.

These and other state management services in ASP.NET 2.0 use the provider model pictured in Figure 1-1 to maximize storage flexibility. Providers abstract storage media in much the same way that device drivers abstract hardware devices. The membership service is equally at home using SQL Server or Active Directory, because ASP.NET 2.0 includes providers for each. Moreover, ASP.NET 2.0 can be extended with custom providers to add support for Web services, Oracle databases, SQL Server databases with custom schemas, and other media not supported by the built-in providers.

The Windows Communication Foundation (or WCF) is an application programming interface in the .NET Framework for building connected, service-oriented applications. or “WCF is a unification of .NET framework communication technologies “.
