• Setup Project

• Extensibility Project

• SQL Server Reporting Services

• Office Projects

Server Controls

• Programmable, server-side objects Properties, methods and events

• Encapsulate both behavior and rendering HTML, XML, WML, script, etc.

• You can create server controls Custom controls User controls Or derive from existing controls

ASP.NETASP.NET

• A component that provides a service to a consumer Components potentially have global reach Consumers use a standard Internet protocol

(HTTP) and data format (XML)• Web services can be implemented in many

languages The consumer does not care which

• The basis of B2X applications

What is a Web Service?

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 Platform Neutral Leverage Existing

Standards No Rip and Replace

The Future: WSA• Use the SOAP header!

• WS-Security• WS-Routing• WS-Transaction• WS-ReliableMessaging

• WS-I

Web Services Interoperability Organization (WS-I)

Operational Requirement WS-I Deliverable

• Common definition for Web services

• Profiles

• Implementation scenarios

• Implementation guidance and support for Web services adoption

• Supporting documentation and whitepapers

• Sample code and applications

• Consistent, reliable interoperability between Web services technologies from multiple vendors

• Conformance testing tools

Goal: Promote Web services interoperability across Goal: Promote Web services interoperability across platforms, applications, and programming languagesplatforms, applications, and programming languages

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
