Remarks

A dictionary in which the values are weak. When a value has been garbage- collected, the dictionary acts as if the key is not present (except the Remove() method, which saves time by not checking whether the value is dead.)

This is implemented on top of a standard Dictionary. In order to allow the dictionary to be read safely while it is being enumerated, cleanup operations (to remove entries whose value has been garbage-collected) do not occur automatically during read operations. You can allow cleanups by calling AutoCleanup().
