.NET包括五个方面Tools, Servers, XML Web services, Clients, .NET experiences.

.NET Experience
Description:
.NET experiences are XML Web services that allow you to access  
information across the Internet and from standalone applications in an  
integrated way that saves you time and money. Microsoft will deliver .
NET experiences for individuals and for businesses. Some of the products
that Microsoft is transitioning into .NET experiences are MSN,  
bCentral, Passport, and Microsoft Visual Studio? .NET.

Clients
Description:
Clients are PCs, laptops, workstations, phones, handheld computers,  
Tablet PCs, game consoles, and other smart devices. What makes these  
devices "smart" is their ability to access XML Web services. Smart  
clients use software that supports XML Web services, and enable you to  
access your data regardless of the location, type, and number of clients
you use. Some of the .NET client software Microsoft will offer are  
Windows CE, Windows Embedded, Window 2000, and the upcoming Windows XP.
This software will power PCs, laptops, workstations, smart phones,  
handheld computers, Tablet PCs, and XBox? game consoles.

Services
Description:
In addition to developers creating XML Web services, Microsoft is  
creating a core set of building block services that perform routine  
tasks and act as the backbone for developers to build upon. The first  
set of XML Web services being built, known as .NET My Services (the  
product formerly code-named "HailStorm") is user-centric services  
oriented around people, rather than specific devices, networks, or  
applications. .NET My Services is based upon the Microsoft Passport user
authentication system. With .NET My Services, users receive relevant  
information, as they need it, delivered to the devices they're using,  
and based on preferences they have established.

Web Sites vs. XML Web Services

Web sites are about presenting information to a user: they are the  
communication vehicle for servers to talk to users. XML Web services  
offer a direct means for applications to interact with other  
applications. Applications hosted internally, as well as on remote  
systems, can communicate via the Internet by using XML and SOAP  
messages.

Servers:
Description:
The Microsoft .NET Enterprise Servers, including the Microsoft  
Windows? 2000 server family, make up the Microsoft .NET server  
infrastructure for deploying, managing, and orchestrating XML Web  
services. Designed with mission-critical performance in mind, they  
provide enterprises with the agility they need to integrate their  
systems, applications, and partners through XML Web services, and the  
flexibility to adapt to changing business requirements. The .NET  
Enterprise Servers are:  

Microsoft Windows .NET Server to build, deploy, manage, and run  
XML-based Web services.  
Microsoft Application Center 2000 to deploy and manage highly  
available and scalable Web applications.  
Microsoft BizTalk? Server 2000 to build XML-based business processes  
across applications and organizations.  
Microsoft Commerce Server 2000 for quickly building scalable  
e-commerce solutions.  
Microsoft Content Management Server 2001 to manage content for dynamic  
e-business Web sites.  
Microsoft Exchange Server 2000 to enable messaging and collaboration  
anytime, anywhere.  
Microsoft Host Integration Server 2000 for bridging to data and  
applications on legacy systems.  
Microsoft Internet Security and Acceleration Server 2000 for secure,  
fast Internet connectivity.  
Microsoft Mobile Information 2001 Server to enable application support  
by mobile devices like cell phones.  
Microsoft SharePoint? Portal Server 2001 to find, share, and publish  
business information.  
Microsoft SQL Server? 2000 to store, retrieve, and analyze structured  
XML data.

Tools
Description:
Microsoft Visual Studio? .NET and the Microsoft .NET Framework supply  
a complete solution for developers to build, deploy, and run XML Web  
services. They maximize the performance, reliability, and security of  
XML Web services.

Visual Studio .NET is the next generation of Microsoft's popular  
multi-language development tool, built especially for .NET. Visual  
Studio .NET helps developers quickly build XML Web services and  
applications that scale easily, using the language of their choice.  
Visual Studio .NET advances the high-productivity programming  
languages Microsoft Visual Basic?, which includes new object oriented  
programming features; Microsoft Visual C++?, which advances Windows?  
development and enables you to build .NET applications; and C#, which  
brings RAD to the C and C++ developer.  

The .NET Framework is a high-productivity, standards-based,  
multi-language application execution environment that handles  
essential plumbing chores and eases deployment. It provides an  
application execution environment that manages memory, addresses  
versioning issues, and improves the reliability, scalability, and  
security of your application. The .NET Framework consists of several  
parts, including the Common Language Runtime, a rich set of class  
libraries for building XML Web services, and ASP .NET.
