LyncClient Class (Lync Model API)

The Microsoft.Lync.Model.LyncClient class is the basis for all Microsoft Lync 2010 API functionality. This class exposes a static method, LyncClient.GetClient, that you call to get an instance of the Microsoft.Lync.Model.LyncClient class before initiating any further Lync 2010 API logic. All subsequent application logic uses this class instance for Lync 2010 API features.

The Microsoft.Lync.Model.LyncClient instance uses the endpoint established by a running instance of Microsoft Lync 2010. When you sign in, sign out, start or accept a conversation, add contacts or custom groups, you are actually performing these actions using the Lync 2010 endpoint. As your custom application performs these actions, you see these actions mirrored in Lync 2010.

Important note Important

For the call to the LyncClient.GetClient method to succeed, Lync 2010 must be running on the local computer.

The Microsoft.Lync.Model.LyncClient class lets you verify that your local user is signed in to Lync Server 2010. If not signed in then you call the LyncClient.BeginSignIn method to sign the local user in. If the local user is already signed in to Lync Server 2010, calling this method raises an exception. You should read the Client.State property to discover the sign-in state before attempting to sign in.

You can also sign the user out of Lync Server 2010 using the Microsoft.Lync.Model.LyncClient instance. A call to the LyncClient.BeginSignOut method raises an exception if the user not signed in to Lync Server 2010.

The sign-in/sign-out process is asynchronous and requires that you handle events raised by the Microsoft.Lync.Model.LyncClient instance when you have called either of the previous methods. For information about asynchronous programming in Lync 2010 API, see Lync Asynchronous Programming (Lync 2010 SDK).

The following figure illustrates the classes you obtain from the Microsoft.Lync.Model.LyncClient class. Note that these client classes expose member methods and classes for more specific functionality.

Conversation Manager

To start a new conversation with another user or join a conference, you get an instance of the Microsoft.Lync.Model.Conversation.ConversationManager class from your Microsoft.Lync.Model.LyncClient instance. The conversation manager exposes a collection of current conversations as well as a collection of properties describing previous conversations. You obtain the voice mails manager class from the conversation manager so that you can access the Outlook voicemail system for retrieving voice mail.

Contacts and Groups Manager

The contacts and groups manager class (Microsoft.Lync.Model.Conversation.ConversationManager) gives you access to the local user's contact list. Through this class, you can:

  • Enumerate the contact list and the group list.

  • Add and remove contacts and distribution groups from the contact list.

  • Add and remove contacts from custom groups.

  • Add, remove, and rename custom groups.

  • Enumerate the contacts in a distribution group.

Self

The Microsoft.Lync.Model.Self class allows you to:

  • Publish a set of the local user’s telephone numbers for other users to use.

  • Set many user options for customization.

Delegator Client

The Microsoft.Lync.Model.DelegatorClient class allows your user to assign a team member such as an administrative assistant to the responsibility of answering incoming telephone calls on your user's behalf.

Utilities

The Microsoft.Lync.Model.Utilities class provides features such as email sending, meeting scheduling, a device-tuning wizard, adding contacts to Outlook, and accessing previous conversations stored in Microsoft Outlook.

Device Manager

The Microsoft.Lync.Model.Device.DeviceManager class lets you discover the device for audio and video transmissions and play an audio file on a specified playback device.
