Does anyone have idea on how to create category in contact by C#?
I guess it should use the createItemRequest. But my following code doesn't work:

var req = new GroupWise.createItemRequest();
req.item = new GroupWise.Category();
req.item.name = "my category";
config.Login.createItemRequest(req);

I might need to specify it's under contact, but I don't know how.

Thanks in advance!
