You can let your users access their contacts and appointments so they can share content, email, calendar info, or messages with each other, or whatever functionality you design.
To see a few different ways in which your app can access contacts and appointments, see these topics:
| Topic | Description |
|---|---|
| Select contacts | Through the Windows.ApplicationModel.Contacts namespace, you have several options for selecting contacts. Here, we'll show you how to select a single contact or multiple contacts, and we'll show you how to configure the contact picker to retrieve only the contact information that your app needs. |
| Send email | Shows how to launch the compose email dialog to allow the user to send an email message. You can pre-populate the fields of the email with data before showing the dialog. The message will not be sent until the user taps the send button. |
| Send an SMS message | This topic shows you how to launch the compose SMS dialog to allow the user to send an SMS message. You can pre-populate the fields of the SMS with data before showing the dialog. The message will not be sent until the user taps the send button. |
| Manage appointments | Through the Windows.ApplicationModel.Appointments namespace, you can create and manage appointments in a user's calendar app. Here, we'll show you how to create an appointment, add it to a calendar app, replace it in the calendar app, and remove it from the calendar app. We'll also show how to display a time span for a calendar app and create an appointment-recurrence object. |
| Connect your app to actions on a contact card | Shows how to make your app appear next to actions on a contact card or mini contact card. Users can choose your app to perform an action such as open a profile page, place a call, or send a message. |
