Removes all associations for a primary object.
Assembly: System (in System.dll)
primary is a null reference (Nothing in Visual Basic).
The method removes all associations between a primary object and all of its secondary objects, created by calls to the CreateAssociation method.
A WeakReference is used to maintain the association between the primary and secondary object; therefore, this method does not influence when either the primary of secondary objects are finalized or reclaimed by garbage collection.
