If you are creating a new type of project for Visual Studio probably you are implementing a VSIX (former VS Package)

To add a new Menu Item to Project Item Contextual Menu you need to declare a vsct file in your package, and inside VSCT attach your new menu item to Project Item Menu GUID

do you want to make an AddIn for Visual Studio? There is plenty of doc and samples for this, for example:
