Extending VisualStudio

I want to extend Visual Studio such that, when someone right clicks on Solution Explorer, context menu should have a new menu item, say "Open custom form", clicking which should open a f开发者_JAVA百科orm (this form would actually accept some settings and modify config file accordingly)

Q1. Please provide on where should I start for such extension. Couldn't find any reference/tutorial link :( Q2. What technology can be used to make such a form - Winforms/WPF?

Either Windows Forms or WPF should be fine.

• Google Code: explorer-popup-add-in

There's a lot of docs on Visual Studio integration here
