• privateGamerSlots
  Type: Int32
  Number of reserved private session slots created for the session. This value must be less than maximumGamers.
• sessionProperties
  Type: NetworkSessionProperties
  Properties of the session being created.
• callback
  Type: AsyncCallback
  The method to be called once the asynchronous operation is finished.
• asyncState

Exceptions

Exception type	Condition
ArgumentOutOfRangeException	One of the following conditions is true: maxGamers is not in the range of gamers that are supported in a network session. The XNA Framework supports multiplayer sessions between two and 31 players in a session for a Windows or an Xbox 360 game. privateGamerSlots is less than 0 or greater than maximumGamers.
InvalidOperationException	One of the following conditions is true: A different session already exists. There can be only one NetworkSession or AvailableNetworkSessionCollection in use at a time. You must dispose any previous session before you create a new one. One of the following methods has been called, but has not yet returned results: NetworkSession.Create NetworkSession.BeginCreate NetworkSession.Find NetworkSession.BeginFind NetworkSession.Join NetworkSession.BeginJoin Note that you must wait for any of these methods to return before you can create a new network session. To support this, you may use the asynchronous methods BeginCreate, BeginFind, BeginJoin, and the corresponding EndCreate, EndFind, EndJoin methods to detect when the operation is complete.
ObjectDisposedException	This NetworkSession is disposed.

Remarks

Call EndCreate to get results of the call to BeginCreate.
