SingletonClassFactory

Overview

This class factory allows you to publish a service that follows the Singleton pattern, meaning, that exactly one instance of the service class will be created at a given time and used to serve all requests.

Using the SingletonBehavior option, you can control how concurrent access to the service will be handled, by allowing simultaneous concurrent access (SingletonBehavior.Multiple), by synchronizing all requests so only one of them will be executed at a given time (SingletonBehavior.Wait) or by causing concurrent calls to fail (SingletonBehavior.Fail).
