Some Application Types • • Windows Forms Web Service Windows Service Console Application Class Library Smart Device Application • Mobile Web Application • Windows Control • • • Library Web Control Library Setup Project Extensibility Project SQL Server Reporting Services Office Projects

Server Controls • Programmable, server-side objects • • ü Properties, methods and events Encapsulate both behavior and rendering ü HTML, XML, WML, script, etc. You can create server controls ü Custom controls ü User controls ü Or derive from existing controls

What is a Web Service? • • • A component that provides a service to a consumer ü Components potentially have global reach ü Consumers use a standard Internet protocol (HTTP) and data format (XML) Web services can be implemented in many languages ü The consumer does not care which The basis of B 2 X applications

XML Web Services Explained • • • Internet connects entities together Email and WWW inherently cross boundaries XML Web Services applies the same platform neutral approach to system integration ü Platform Neutral ü Leverage Existing ü E-mail WWW Web Services Connects People to Information Connects Applications Standards No Rip and Replace

The Future: WSA • Use the SOAP header! • • WS-Security WS-Routing WS-Transaction WS-Reliable. Messaging • WS-I

Web Services Interoperability Organization (WS-I) Goal: Promote Web services interoperability across platforms, applications, and programming languages Operational Requirement WS-I Deliverable • Common definition for Web • Profiles services • Implementation scenarios • Implementation guidance and • Supporting documentation support for Web services adoption • Consistent, reliable interoperability between Web services technologies from multiple vendors and whitepapers • Sample code and applications • Conformance testing tools

WS-I Profiles • Profile: Group of Web services specifications at specific version levels • Profiles make it easier to discuss Web services interoperability • First profile: WS-I Basic XML Schema 1. 0 SOAP 1. 1 WSDL 1. 1 UDDI 1. 0
