Passing null as the filename parameter will cause default remoting initialization without requiring the existence of a configuration file.
For configuration file syntax, see [<topic://gnconremotingsettingsschema>].
Marshal-by-reference objects (MBRs) do not reside in memory forever. Instead, unless the type overrides MarshalByRefObject.InitializeLifetimeService to control its own lifetime policies, each MBR has a finite lifetime before the .NET Framework remoting system begins the process of deleting it and reclaiming the memory. For more information, see Lifetime Leases.
