install missing namespace in cAlgo "using System.Windows.forms;"

Hi, I have a question regarding using some C# functionality, like windows form or other.
I would like to add this namespace in my EA & indicator

using System.Windows.forms;

but .forms class is missing. it would be a great help someone can guide me on how to install missing namespace classes in cAlgo. to use additional features.

Like we use in VisualStudio.
