Visual Basic .NET (VB.NET) is an Object-Oriented computer language that can be viewed as an evolution of Microsoft’s Visual Basic (VB) implemented on the Microsoft .NET framework. The .NET Framework contains a virtual machine called Common Intermediate Language (CIL). Simply put, programs are compiled to produce CIL and the CIL is distributed to user to run on a virtual machine. VB.NET, C++, C# compilers are available from Microsoft for creating CIL. In DB-VA you can generate C# persistent source code and DLL files, so you can reference the DLL file and Persistent Library in Visual Studio .NET 2003 and develop the VB.NET application.

In the following section, you will develop a VB.NET application. The application is exactly the same as the one in Chapter 4 – Developing Standalone .NET Application sample but this time you use VB.NET instead of C# for development. You need to download Chapter 4 sample application because it contains the DLL file and persistent libraries for your VB.NET project.
