Course description

In this course, you’ll learn how to use Visual Basic .NET to build ASP.NET Web pages and XML Web services. You’ll gain an understanding of the new architecture behind ASP.NET and how to use the new server controls. You also learn how to use ADO.NET to create data-driven ASP.NET Web forms. You’ll learn to inter-operate with non-.NET code, to manage session state, to re-use code by creating your own controls, to improve performance with output caching, to debug your application and trace its activity, to use advanced Web services features, to configure and deploy ASP.NET applications, to authenticate users and limit their access to resources, to handle multi-user data access conflicts, and to support mobile devices.
