.NET TECHNOLOGY

1. The .NET Framework Technology The .NET Framework Technology

2. Why .NET?Why .NET?
–Interoperability between languages and
execution environments
–Uniformity in schema or formats for Data
Exchange using XML, XSL
–Extend or use existing code that is valid
–Programming complexity of environment is
reduced

3. The .NET Framework is…The .NET Framework is…
•A COMPONENT MODEL FOR THE INTERNET
–The new approach to building large scale
distributed systems for the Internet
–Provides the capability to integrate multiple
devices
–Built around the tools and protocols (XML,
WSDL, SOAP, HTTP) that are becoming
standard on the Internet

4. The .NET Framework Design GoalsThe .NET Framework Design Goals
–Component Development for the Internet
–"Cross-Language Development”
•Inheritance, Debugging, Exception handling
–Reliability and Security
–Simple Development and Deployment
–Device-agnostic

15. .NET Classes.NET Classes
•Namespaces and Classes
–Hierarchical, unified, extensible class libraries
–Provide “system” and base functionality and services
–Everything is an object!
•Interfaces
–The .NET (Service) contracts
•Types
–Byte, Sbyte, Single, Double, String, Int16, Int32, Int64
etc.
–Common Type System - “Common Type Denominator”
