.Net Training Overview |
This course provides a realistic, hands-on, comprehensive coverage of developing Web services using ASP.NET and Visual Basic. Web services are an evolving series of standards that enable programs on various computers to communicate with other programs on similar or disparate computers transparently over the Internet. This course teaches in detail the skills needed to program Web services using ASP.NET. It also examines the fundamentals of SOAP and WSDL essential for creating interoperable Web services. The course is current to .NET 3.5 and Visual Studio 2008, with coverage of newer features such as the WS-I Basic Profile 1.1, SOAP 1.2, event pattern for calling Web services asynchronously, and more. It also includes an introduction to Windows Communication Foundation (WCF), Microsoft’s modern unified framework for creating distributed applications.
The first chapter introduces Web services and Service Oriented Architecture (SOA). The baseline Web service specifications of XML, SOAP, WSDL and UDDI are outlined.
Chapter 2 covers the fundamentals of SOAP and WSDL. Web services are developed using the .NET Framework SDK. Chapter 3 covers the details of how to create and debug ASP.NET Web services using Visual Studio 2008.
Chapter 4 shows how to create clients for Web services using an SDK tool and using Visual Studio 2008. Sophisticated topics, such as state management, caching and transactions in Web services are covered in Chapter 5. The next three chapters discuss important technologies at the foundation of ASP.NET Web services, including XML serialization, SOAP and WSDL.
Chapter 9 provides a practical discussion of data access using Web services. The course concludes with an introduction to Windows Communication Foundation.
.Net Training Prerequisites
Knowledge of the .NET Framework using Visual Basic and an understanding of the fundamentals of XML. Some experience in ASP.NET is advantageous.

Appendix B. Configuring IIS for ASP.NET
Required software is Visual Studio 2008, Standard Edition or higher. The recommended operating system is Windows XP with at least Service Pack 2. Internet Information Services should be installed. Service Pack 1 for Visual Studio 2008 is recommended. See the course Setup Notes for details.
A good minimal hardware profile for this course would have a 2 GHz or better CPU, 512 MB of RAM, and at least 4 GB of free disk space for tools installation and courseware. The installation of Visual Studio 2008 Service Pack 1 requires 5.5 GB of free disk space on the partition on which the operating system is installed.
