ENTERPRISE DEVELOPMENT IN VISUAL BASIC .NET
| Course Description |

This course is focused on the "back end" part of Enterprise programming, not the user interface. The sample applications are Windows applications, to keep the pre-requisites to a minimum. You'll be able to use these same concepts as the back end to a web (ASP.NET) application, as well.
Course Length: 3 Days
Course Tuition: $1190 (US)
