How to use Visual Studio Tool?

Hi,

While installing CorelDRAW Graphics Suite, a component called "Visual Studio Tools for Applications" has been installed. I'm a programmer and I have Visual Studio 2013 Pro installed on my computer. I thought this component is going to add some extensions to VS, so I can use it to make plugins or other stuff for CorelDraw, but I cannot find anything related to CorelDraw in VS.

Does anyone know how can I use VS to develop stuff for CorelDRAW Graphics Suite?

Thanks!
