ConferenceSession.BeginJoin Method (AsyncCallback, Object)
NOTE: This API is now obsolete.
This method will be removed from future versions. Instead, use BeginJoin(ConferenceJoinOptions, AsyncCallback, Object) to join a conference. Creates and joins an ad-hoc conference.

public IAsyncResult BeginJoin(
AsyncCallback userCallback,
Object state
)
Parameters
- userCallback
Type: System.AsyncCallback
The method to be called when the asynchronous operation is completed.
- state
Type: System.Object
A user-provided object that distinguishes this particular asynchronous operation from other asynchronous operations.
Return Value
Type: System.IAsyncResult
An IAsyncResult that references the asynchronous operation.
Exceptions
| Exception | Condition |
|---|---|
| InvalidOperationException | Thrown when the operation is not valid at the given conference session state. |
Remarks
Joining a conference is required to receive roster events on the ConferenceSession and McuSession derivatives.
The platform schedules a conference valid for 8 hours with an MCU for all the available MCU factories. However, the audio-video MCU will only be scheduled if inband provisioning data for the endpoint is available and indicates that the endpoint owner is provisioned for audio.
