HI There are no major architectural changes included with this release; .NET Framework 3.0 uses the Common Language Runtime of .NET Framework 2.0 1.Includes a new set of managed code APIs that are an integral part of Windows Vista and Windows Server 2008 operating systems. It is also available for Windows XP SP2 and Windows Server 2003 as a download. 2. Windows Presentation Foundation (WPF) formerly code-named Avalon; a new user interface subsystem and API based on XML and vector graphics which uses 3D computer graphics hardware and Direct3D technologies. See WPF SDK for developer articles and documentation on WPF. 3. 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. 4 Windows Workflow Foundation (WF) allows for building of task automation and integrated transactions using workflows. 5 Windows CardSpace 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.

there are many features is 3.0 version The local type inference that means that we can use the keyword var to define types so you can use variables without worrying about thier types Lambda expression witch enables us to define anonymous methods with more precision Extention methods other than the classic way and I mean here the inheritence; you can extend an object without deriving it Object initialization; I give an example classic way2.0 : Person oPerson = new Person(); oPerson .FirstName = Bejaoui; oPerson.LastName = Bechir; New Version3.0 Person o Person = new Person{FirstName = Bejaoui; LastName=Bechir} Anounimous types var oPerson = new Person(); Query expression Linq witch allows us query objects within the application exactly like querrying object from a database using sql That's all
