I am developing an add-in for visual studio. I want to give it the look and feel of an add-in to the user.While designing the interfaces, should I follow the look and feel of normal visual studio environment or does it required to appear special to highlight the add-in's forms, toolWindows, buttons to the end user in a specific theme.
What I want to know is are there any design guidelines that I should follow in making my addin interfaces?
help with some related references would be appriciated
