Enumerating devices (HTML)

Applies to Windows and Windows Phone

Purpose

The Windows.Devices.Enumeration and Windows.Devices.Enumeration.Pnp namespaces enable you to enumerate devices. The following are typical reasons to enumerate devices:

  • Selecting the device to be used by an application. For example, a voice chat application may use the API to present a list of microphones or webcams for the user to select from, or a photo import app may use the API to present a list of removable storage devices for the user to select from.
  • Device discovery and notifications about devices, for apps that use them, such as Windows Store device apps.
