Remarks

This function creates a new game session and adds the current members of the lobby session to the game session, if a game session doesn't already exist. If a new user joins the lobby session after a game session is already created, this function finds the existing game session in Multiplayer Session Directory (MPSD) by using a transfer handle in the lobby session, and then adds the new user to the game session using that transfer handle. For more information, see Multiplayer concepts overview. If a lobby session doesn't exist, likely because XblMultiplayerManagerInitialize wasn't called before calling this function, an error occurs. An error also occurs if matchmaking is in progress. This function does not migrate existing lobby session properties to the game session.
The result of this function is delivered as a multiplayer event with an event type set to XblMultiplayerEventType::JoinGameCompleted. You can call XblMultiplayerManagerDoWork to retrieve multiplayer events.
When attempting to join a lobby session, the service returns HTTP_E_STATUS_BAD_REQUEST if the server is full.
After joining, you can set the properties for the game session by calling XblMultiplayerManagerGameSessionSetProperties or XblMultiplayerManagerGameSessionSetSynchronizedProperties, or you can set the host for the game session by calling XblMultiplayerManagerGameSessionSetSynchronizedHost.
