.NET Framework 2.0 consists of four major new components:
Generics
Language support for generics built directly into the .NET CLR.
Full 64-bit support for both the x64 and the IA-64 hardware platforms.
Numerous API changes.
SQL Server integration – .NET 2.0, VS 2005, and SQL Server 2005 are all tied together. This means that instead of using T-SQL, one can build stored procedures and triggers in any of the
New data controls with declarative data binding.
New personalization features for ASP.NET, such as support for themes, skins, master pages and webparts.
.NET Micro Framework – a version of the .NET Framework related to the Smart Personal Objects Technology initiative.
Membership provider
Partial classes
Nullable types
Anonymous methods
Iterators
Data tables


.NET Framework 3.0

.NET Framework 3.0, formerly called WinFX was released on 21 November 2006. It 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
.NET Framework 3.0 consists of four major new components:
Windows Presentation Foundation (WPF)
Windows Communication Foundation (WCF)

.NET Framework 3.5

Version 3.5 of the .NET Framework was released on 19 November 2007, but it is not included with Windows Server 2008. As with .NET Framework 3.0, version 3.5 uses the CLR of version 2.0. In addition, it installs .NET Framework 2.0 SP1, (installs .NET Framework 2.0 SP2 with 3.5 SP1) and .NET Framework 3.0 SP1 (installs .NET Framework 3.0 SP2 with 3.5 SP1), which adds some methods and properties to the BCL classes in version 2.0 which are required for version 3.5 features such as Language Integrated Query (LINQ).

Basic components of .NET platform

What are the basic components of .NET platform? The basic components of .NET platform (framework) are: Common Language Runtime (CLR): The most important part of the .NET Framework is the .Net Common Language Runtime (CLR) also called .Net Runtime in short. It is a framework layer that resides above the Operating System and handles/manages the execution of the .NET applications. Our .Net programs don’t directly communicate with the Operating System but through CLR MSIL (Microsoft Intermediate Language) Code: When we compile our .Net Program using any .Net compliant language like (C#, VB.NET, C++.NET) it does not get converted into the executable binary code but to an intermediate code, called MSIL or IL in short, understandable by CLR. MSIL is an OS and H/w independent code. When the program needs to be executed, this MSIL or intermediate code is converted to binary executable code, called native code. The presence of IL makes it possible the Cross Language Rela...

Did you know… You can go directly to the installed code samples from within Visual Studio?  This tip is specific for Visual Studio 2008. You can easily find the samples that have been installed for Visual Studio by going to   Help-Samples.  Then in the browser, click on the   local Samples folder   link. As the message box states, the samples are in a .zip file, so you’ll need to extract these files before you attempt to build. Otherwise, the build will fail, and you’ll wonder why the samples that came with the product don’t work.
