Overview

• Overview and .NET Evolution
• Design points and Architecture
• Common Language Runtime
• Class Libraries
• Windows Forms
• ASPX
• Web Services

3
The .NET Evolution
Application
Code and data structures
Before COM, applications were completely separate
entities with little or no integration
4
The .NET Evolution
COM provides a way for components to integrate.
However, each component must provide the
plumbing and objects cannot directly interact.
5
The .NET Evolution
With the .NET Framework common language runtime,
components are built on a common substrate. No
plumbing is needed and objects can interact
directly
6
Common Language Runtime

• Manages running code
• Type safety and code access security
• Garbage collection and error handling
• Provides common type system
• Value types (integer, float, etc)
• Objects, Interfaces
• Provides access to system resources
• Native APIs through P/Invoke
• COM integration

Common Language Specification

• Interface between the languages and the class
  libraries
• If you want to develop a library to be used by
  multiple languages, you really have to follow the
  CLS specifications

Design Points

• Simplify development
• More power, less plumbing
• Unify programming models
• Across languages and types
• Web standards and best practices
• Rich XML, standard protocols, stateless
• Easier to deploy, run, maintain
• Versioning and availability

ASP.NET

• ASP.NET is a revolutionary advance of ASP
• Existing ASP skills still work fine
• but lots more features to leverage
• Core themes that ASP.NET has focused on
• Making it easier to build, deploy, and operate
• Providing great performance and scalability
• Supported platforms
• Windows 2000 and Windows XP
• Open hosting APIs

23
ASP.NET Development

• Server controls encapsulate behavior
• Provide VB-Like Model
• Support compiled languages
• VB, C, JScript, COBOL, etc.
• Enable separation of code from content
• Work independently
• Support multiple clients automatically
• Mobile controls for small devices

24
ASP.NET Web Services

• Simple Programming Model
• Author .asmx files
• SOAP messages mapped to methods
• HTTP or XML knowledge not required
• Multiple Message Formats
• SOAP messaging support
• HTTP Get/Post
• Extensible model for innovation
