I needed a GUI interface to connect to IB Gateway in order to streamline the automated trading strategies, gather account data, perform risk and order management, generate/place orders and generate/email reports. I found building GUI on Visual Studio was quite straight forward and hence built this GUI interface for IB Gateway. I have chosen the C# API because I found it to be stable. I have open-sourced the source code, so that everyone can use it!
You can download or clone the source code via GitHub online code repository.
