Behavior of Local Sessions

XNA Game Studio 3.0 introduces a change in the behavior of network sessions when local profiles sign out in the middle of a session. In previous versions of XNA Game Studio, a session would end whenever a player signed out. Now, profiles that sign out are removed from the session, and the session will be ended only if there are no suitable players left in the session.

Platforms

Xbox 360, Windows XP SP2, Windows Vista, Zune
