Remarks

Distributed garbage collection controls when server applications can be deleted. Traditionally, distributed garbage collection uses reference counts and pinging for control. This works well when there are a few clients per object, but does not work well when there are thousands of clients per each object. The lifetime service can assume the function of a traditional distributed garbage collector, and scales well when the number of clients increases.

The lifetime service associates a lease with each remotely activated object. When the lease expires, the object is removed. A lease can specify that an object has an infinite lifetime.

Each AppDomain contains a lease manager that administers the leases in the domain. The lease manager periodically examines the leases for time expiration. If a lease has expired, it can either be canceled by removing its reference to the lease, or renewed by invoking one or more of the lease's sponsors.

A lease contains properties that determine its policies, and methods that renew the lease time. The lease exposes the ILease interface.
