Origins of .NET

.NET originally called NGWS “Next Generation Windows Services” The term NGWS was used for

Microsoft’s plans for producing an ‘Internet-based platform of Next Generation Windows Services’

Created to Compete With Sun’s Java platform

Origins of .NET

Original Plans Announced in June 2000:•.NET is Microsoft's new Internet and Web strategy

•.NET is NOT a new operating system •.NET is a new Internet and Web based infrastructure •.NET delivers software as Web Services •.NET is a framework for universal services •.NET is a server centric computing model •.NET will run in any browser on any platform •.NET is based on the newest Web standards

Development

Who was involved in the creation of it? Bill Gates oversaw the .NET project

What environment was it created in? Created in a corporate environment,

by the Microsoft Corporation.

Development

Did it start out as something simpler? .NET is an ongoing project, and if

anything it started out as something more complex. It has yet to catch on in a way that Microsoft originally expected it to.

What is .NET? .NET is a bunch of different software

and hardware made to be .NET compatible

Four basic elements of .NET technology: Web Services Smart Clients .NET servers .NET development tools

Web Services

Web services are the backbone of .NET Small units of code with specific tasks Code then linked together using XML

based protocols Since XML is used, web services can

be used across networks regardless of programming language

Development Tools

Visual Studio .NET Used for creating .NET compatible

applications Includes new versions of old languages

that will automatically create XML files needed to turn processes into web services

Includes Microsoft’s new language C#; basically Microsoft’s version of Java.

Servers and Smart Clients

.NET Servers A bunch of new software that will

make Microsoft based servers able to access .NET Web Services

Smart Clients Software and Mobile devices that are

made to be compatible with .NET Web Services.

What Can it Do? Allows programs written in old

languages to be integrated with new software.

Can create software that can be used across any language and over any browser.

Can re-use web services created by other people and shared over the internet.

Limitations

Major limitation for .NET is that it can only be used on Windows based machines only.

Is it easy to use? Visual Studio .NET includes enough

features to make the transfer to .NET development pretty simple.
