C# And windows explorer context menu?

I have an idea for a little C# program, where I want to be able to right click on a file in windows explorer and somehow 'tag' that file. Subsequent right clicks would show it's tagged state.

Bottom line is that I need to be able to right click on a file, see a custom menu item and perform a custom action as well as visualize some info.

Neve开发者_如何学JAVAr having done this, I'm not even sure where to start... :)

Any good example out there? Things I should read up on? Links?

Thanks!
