The .NET Framework -Technology in Education


2/30

Why .NET?

Interoperability between languages andexecution environments

Uniformity in schema or formats forData Exchange using XML, XSL

Extend or use existing code that is valid

Programming complexity ofenvironment is reduced


3/30

The .NET Framework is

A COMPONENT MODEL FOR THE INTERNET

The new approach to building large scaledistributed systems for the Internet

Provides the capability to integrate multipledevices

Built around the tools and protocols (XML,WSDL, SOAP, HTTP) that are becomingstandard on the Internet


4/30

The .NET Framework Design Goals

Component Development for the Internet

"Cross-Language Development

Inheritance, Debugging, Exceptionhandling

Reliability and Security

Simple Development and Deployment Device-agnostic

Visual Studio .NET

Increased programming productivity Easier to write code: drag and drop Web App and Services

Development. Fully supports the .NET Framework

Simplified development Multi-language support Improved debugging Unified IDE

Powerful design tools Windows Forms, Web Forms XML and component designers Consistent set of tools across languages


14/30

The .NETCompactFramework

Designed specifically for smart devices Lightweight architecture Compatible subset of desktop platform Visual Studio.NET used for app development Adaptable to different application needs Build Smart Device applications in Visual Studio

.NET

Broad availability Across multiple CPUs Across Windows CE and third-party RTOSes Across a variety of physical form factors


15/30

.NET Services

What is a Web Service? Unit of application logic providing data and

services over the Web using standard protocols XML Web Services expose additional services

needed to build solutions ASP .NET in the .NET Platform

Building Block Services Basic services used to build applications and Web

Service Examples: www.xmethods.com Access through any Website
http://www.xmethods.com/http://www.xmethods.com/


16/30

XML Web Services FoundationSimple, Open, Broad Industry Support

Ubiquitous Communications: Internet

Universal Data Format:XML

Service Interactions: SOAP

Publish, Find, Use Services: UDDI


17/30

How .NET Makes Web Services Possible

.NET is built on Internet standard protocols Uses Framework classes, such as System.Web.Services

Enables communication through open standards XML

Service description expressed with WSDL SOAP

Basic wire format Universal Description Discovery Integration (UDDI)

HTTP


18/30

.NET Key Benefits

Object-oriented model

Namespace and Framework structure

Freedom to Choose

The language that meets your needs

The development tool that will make it easier to

learn programming


19/30

Motivations for Academia

Students need to be stimulated withinteresting/challenging ideas and problems

Industry focused students want skillsrelevant to their workplace

Research - The Microsoft Shared SourceCLI (Rotor)


22/30

Motivations for Academia

Visualization of fundamental computingconcepts

Visual Studio .NET Features: Class Browser,

Object Browser, ILDasm, etc

Rich framework libraries

Leverage namespace/functions teach more CS

concepts Teach advanced concepts earlier in the course
