I can't find a way (searching through MagicDraw and its doc as well as Goolge) to make MagicDraw show an Interface as it is defined in UML with the stereotype notation << interface >> instead of just coloring it green and drawing a circle in the right corner.
Could someone give me a hint on how to display interfaces like that in MagicDraw please.
PS: does MagicDraw 16.8 have a default way how to draw .Net (C#) properties?
I know this is a very old question, but in case anyone else wants to know the answer (as it was my case when I arrived to this post):
In the Containment window, right-click on the Data folder and select New Element -> Stereotype.
In the new element << >> that appears under the Data folder, rename it Interface.
In the main UML window, right-click on your own interface symbol and select Stereotype -> Interface [Element] (this last item in the Stereotype list appears when you create it following the steps above).
This was tested in MagicDraw version 16.
