Beskrivelse This three-day instructor led course provides delegates with the knowledge and skills that are required to develop XML Web services-based solutions to solve common problems in the distributed application domain. The course focuses on using Microsoft® Visual Studio® .NET, Microsoft ASP.NET, and Universal Description, Discovery, and Integration (UDDI) to enable students to build, deploy, locate, and consume Extensible Markup Language (XML) Web services.
Forudsætninger
Delegates are required to meet the following prerequisites:
- An understanding of how to read and write XML documents.
- Experimented with simple C# applications.
- Developed distributed applications by using Microsoft Visual Basic®, Java, or C++.
