Developing XML Web Services Using Microsoft ASP.NET (M2524)
This course is not currently offered by Global Knowledge. Information here is provided for reference only.
This course provides you with the knowledge and skills that are required to develop Extensible Markup Language (XML) Web services-based solutions to solve common problems in the distributed application domain. The course focuses on using Microsoft Visual Studio .NET and Microsoft ASP.NET to enable you to build, deploy, locate, and consume Web services.
This course incorporates materials from the Official Microsoft Learning Products (OMLPs):

- Implement a simple Web service by using Visual Studio .NET
- Publish and deploy a Web service
- Secure a Web service
- Implement caching in a Web service
- Evaluate the trade-offs and issues that are involved in designing a real-world Web service
- Implement nonstandard Web services such as Hypertext Markup Language (HTML) screen scraping and aggregating Web services
