# Implementing Visual Basic .NET

Our VB.NET code is provided for demonstration purposes only; there is no pure, standalone VB.NET-based TWS API library. Both our "VB\_API\_Sample" and the VB.NET "Testbed" projects included with our TWS API releases call the C# TWS API source. The provided VB.NET code only interfaces with the C# source. Please keep in mind that these samples are in VB.NET, not Visual Basic for Applications.
