.NET: Enterprise Web Development

Course Overview

In today's Internet-dependent world, organisations require enterprise Web applications on which they can rely. Visual Studio 2005 and .NET 2.0/3.0 expedite the development of scalable, secure and reliable Web applications.

This course provides the skills to plan and create multitier applications. You learn to write business logic using C# and VB 2005, access data with ADO.NET, and present Web content with ASP.NET. You also learn to exploit Web services and message queuing to implement service-oriented architectures.

Audience

This course is valuable for those programming robust business Web applications. OO programming experience at the level of Course 419, " C# Programming ", or Course 503, " Visual Basic 2005 Programming ", is assumed.
