1. DOTNET Technologies CHAPTER I
.NET Initiative
Understanding .Net Initiative
Products in .NET suite
Framework components and applications

2. Introduction
An Initiative originates by many users or deployers concurrently.
In 2000’s this .Net was launched by MICROSOFT and developed many applications and services.
Changes the Desktop Applications to Distributed Computing.
It contains many products
VS.NET takes the vital role for exploring this .NET communication process
Provides a special computing environment for multi service
Initiative – Plan, Proposal, Idea, scheme, program, project, inventiveness

3. Understanding .Net Initiative
Today’s Applications
Are User-friendly, easy access
But not Platform-Independent
Ex. Single Process (Search/Browse)  Single Application or Environment
In a Scenario – that two application in two different platforms as below may have some restrictions in accessing.
No complete Interoperability is offered. (ie) Window application can’t run on Linux platform.
.NET bridges this gap between applications.
Applications enables or improves this accessing methods by some special resources, features and techniques.
LINUX
WINDOWS
Access together

4. Concept of .NET
Application Interoperability enables to access existing data & functionality from different applications run on different platforms.
In Internet
Application can be accessed anywhere.
Two applications can communicate over Internet.
.NET enables applications to communicate with one another.
Two applications need to interoperate
They have to overcome some inherent barriers.
How?
***Interoperability is a property of a product or system, whose interfaces are completely understood, to work with other products or systems, present or future, without any restricted access or implementation.

5. Barriers - Solutions
WEB
Services
XML

6. XML WEB SERVICES
Applications can be created that communicate with each other to serve common purpose without User Interaction called as SERVICES. (Instead of Applications)
Three Keywords in .NET Initiative to use together:
 XML  WEB  SERVICES
XML Web Services are significant outcome of .NET Initiative.
XML Web Services provide software products as services.
To access these products
No need to purchase;
Subscribe to a service;
Use until the end of subscription; if needed it can be extended.
Microsoft offers its own set of web services, called MyServices.
These are based on MicroSoft Passport Authentication Service that runs HOTMAIL.

7. Benefits of .NET Initiative
.NET Initiative includes a product suite that flows …
From .NET Enterprise Servers  To Visual Studio.NET development platform
Two Benefits of .NET Initiative are
Interoperation of Client devices (Used for PC / LAPTOP / Handheld Computers)
Windows XP – uses XML to implement remote assistance and Web Publishing
Windows CE.NET(Windows Compact Embedded.NET) – Used for Wireless Communications; Supports mobile devices)
Enhancements of User Experience
This is the essential quality of .Net Initiative.
Ex. ATM to Transfer money (possible in XML WEB SERVICES)
Other examples of XML Web Services are
MS Passport Authentication Service
Remote Assistance Feature of Win XP

8. Passport Authentication Service and its Advantages
User
Passport Authentication Service
Applications
The Advantages of PAS for user and the service provider are
Easy of deployment
Customized service
Better market coverage

.NET Enterprise Servers:
.NET Initiative require many processes to run all applications simultaneously and manage flow of information between applications and services.
Set of Servers has been developed by MS to achieve high interoperability and availability.

10. View of servers in .NET Enterprise Environment
A family of server products from Microsoft that provides back office services.
.NET Enterprise Servers are extensions to Microsoft's BackOffice suite with enhancements that support the .NET Framework.
However, the first servers introduced with the .NET name in late 2000 were only a re-branding of the traditional Windows DNA (Windows Distributed interNet Applications Architecture) products in order to promote the .NET platform.
.NET enhancements have been gradually added.
Windows Server (formerly .NET Server)
The next generation of the Windows 2000 network operating system with .NET enhancements.
In 2003, .NET Server 2003 was renamed Windows Server 2003.
Application Center 2000
Load balancing, clustering, replication and central management of multiple IIS Web servers.
Cluster is a group of servers that work as single unit.
Supports NLB & CLB (Network & Component Load Balancing)
*** Windows DNA is short for Windows Distributed interNet Applications Arcitecture, a marketing name for a collection of Microsoft technologies that enable the Windows platform and the Internet to work together. Some of the principal technologies comprising DNA include ActiveX, Dynamic HTML (DHTML) and COM.

11. .Net Suite continues.. BizTalk Server 2000 Commerce Server 2000
An integration server based on XML.
Commerce Server 2000
A merchant server with shopping cart and credit card capabilities.
Content Management Server 2001
Manages content published on web sites; includes sample web sites and customization codes.
Exchange Server 2000
An messaging and collaboration server.
Host Integration Server 2000
An extension to SNA (System Network Architecture) server. Provides integration of Windows, AS/400s and mainframes.

12. .Net Suite continues..
Internet Security and Acceleration (ISA) Server 2000
A firewall, Web caching and policy management server. Replaces Microsoft Proxy Server.
Mobile Information 2001 Server
An extension to Exchange Server for mobile users.
SharePoint Portal Server 2001
Helps to create web portals; offers features like version tracking, doc. Publishing, controlling role-based access to manage document streamlining.
SQL Server 2000
Microsoft's database management system (DBMS).

13. .NET Framework A platform for creating XML Web Services.
Provides essential Classes, namespaces, assemblies to create applications.
Three components in .NET
Common Language Runtime
Class Library
ASP.NET ( many more languages created by VS.NET or VC#.NET..)

14. Visual Studio.NET VS.NET VC++.NET VC#.NET VB.NET Web Services
Enterprise Servers
Web Services
Clients
VC++.NET VC#.NET VB.NET
VS.NET

15. Visual Studio.NET
Platform for developing web services and windows applications.
Comprises many languages that share common set of classes and environment.
Languages includes
VB.NET, VC#, VFoxPro, VC++..
Two Advantages are
Common IDE across languages
Easy ASP Programming
