I want to write plug-ins for Adobe products in .NET (C#) (specifically Acrobat Reader and PhotoShop). The requirement is to add a new command in the File menu. So for example in Acrobat Reader, I need to add a new "File >> Open My File" command that displays my dialog to open some file.
I have heard about the Adobe Development Kit. Is there a project type or some wizard in Visual Studio through which a plug-in can be created?
