The Microsoft .NET platform includes a comprehensive family of products,
built on XML and Internet industry standards, that provides for each aspect of
developing, managing, using, and experiencing XML Web services.
XML Web services allow applications to communicate and share data over the
Internet, regardless of operating system or programming language.
There are five areas where Microsoft is building the .NET platform today:
!
.NET experiences
!
Tools
!
Servers
!
XML Web services
!
Clients

.NET experiences are XML Web services that allow you to access information
across the Internet and from stand-alone 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 Microsoft MSN

, 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 rapid application
development (RAD) to the C and C++ developer.
The .NET Framework is a high-productivity, standards-based, multilanguage
application execution environment. It provides an application execution
environment that manages memory and addresses versioning issues. It improves
the reliability, scalability, and security of your application. The .NET
Framework consists of several parts. The Common Language Runtime is a rich
set of class libraries for building XML Web services, and ASP.NET.
The Microsoft .NET Enterprise Servers, including the 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. They also provide the flexibility to adapt to changing business
requirements. The .NET Enterprise Servers are:
!
Microsoft Application Center 2000 for deploying and managing highly
available and scalable Web applications.
!
Microsoft BizTalk
™
Server 2000 for building XML-based business
processes across applications and organizations.

user authentication system. With .NET My Services, users receive relevant
information, when they need it, delivered to the devices they are using, and
based on preferences they have established.
We are in an era of standards-based computing. Standards provide the
foundation for the architectural goal of interoperability. The .NET platform is
built on a foundation of industry standards. Applications built on the .NET
platform take advantage of the gains in interoperability that standards provide.
XML is the universal format for structured data. XML is a set of rules for
designing text formats for data in a way that produces files that are easy to
generate and read, unambiguous, and platform-independent.
Microsoft has been very involved with XML from its conception. XML is
currently managed by the World Wide Web Consortium (W3C), which is the
same formal standards body that owns the Hypertext Markup Language
(HTML) specification.

6 Module 1: The Microsoft .NET Platform and XML SOAP is built on XML. It makes it possible for applications to call each other
in a standard, loosely-coupled way.
If you think of the interactions between XML Web services as a phone call,
XML describes the things that applications say to each other in their
conversations. SOAP describes how they call each other on the phone. How do
you greet the service at the other end? How do you ask for something?
