Overview

This course will provide delegates with the knowledge and skills required to develop Web Services based solutions to solve common problems in the distributed application domain. The course focuses on using the Microsoft Visual Studio .NET, Microsoft Visual C# .NET, Microsoft ASP.NET and Universal Description, Discovery and Integration (UDDI) to enable delegates to build, deploy, locate, and consume Web services.

Leads to examinations

• 70-310: Developing XML Web Services and Server Components with Microsoft Visual Basic .NET and the Microsoft .NET Framework

• 70-320: Developing XML Web Services and Server Components with Microsoft Visual C# and the Microsoft .NET Framework

Prerequisites

Delegates should have an understanding of how to read and write Extensible Markup Language (XML) documents and have experimented with simple C# applications. Delegates should be able to develop distributed applications using Microsoft Visual Basic, Java, or C++.

Delegates will learn how to

• Explain how Web services emerged as a solution to the problems with traditional approaches to designing distributed applications
• Describe the architecture of a Web services-based solution
• Describe the underlying technologies of Web services and explain how the Microsoft .NET framework can be used to implement Web services using these technologies
• Implement a Web service consumer by using Microsoft Visual Studio .NET
• Implement a simple Web Service by using Visual Studio .NET
• Publish and deploy a Web service
• Publish and deploy a Web service
• Secure a Web service
• Evaluate the trade-offs and issues involved in designing a real-world Web Services
• Implement nonstandard Web services such as HyperText Markup Language (HTML) screen scraping and aggregating Web services
