Note

This article applies to Visual Studio 2015. If you're looking for the latest Visual Studio documentation, see Visual Studio documentation. We recommend upgrading to the latest version of Visual Studio. Download it here

A VSPackage that implements menu and toolbar commands by using interop assemblies must:

  • Inform the Visual Studio integrated development environment (IDE) about the commands it supports and whether they are currently enabled.

  • Adhere to the rules (contract) for handling commands.

  • Explicitly implement command handling by using either the IOleCommandTarget or IVsUIHierarchy interface.

    The following describes how to do these tasks.
