Enterprise Development In Visual Basic .NET Course

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.

Comfort with the .NET Framework and coding in Visual Basic .NET, including how to compile and run applications in Visual Studio .NET.
