Singleton services

Ducktion fully supports the Singleton pattern. Any service can be registered as a singleton, ensuring that the same instance is returned every time the service is requested, instead of creating a new instance.

The default singleton mode can be configured. See the Configuration Documentation for more information.

Changing the mode of a service

When you register a service, you can specify the mode of the service. There are several methods to do this:

using TheRealIronDuck.Ducktion.Configurators;
using TheRealIronDuck.Ducktion.Enums;

public class MyMonoConfigurator : MonoDiConfigurator
{
        public void Register(DiContainer container)
        {
            // Mark the service as Singleton
            container.Register<MyService>().Singleton();
            
            // Mark the service as Non Singleton
            container.Register<MyService>().NonSingleton();
            
            // Alias for NonSingleton
            container.Register<MyService>().Transient();
            
            // Specify the singleton mode manually
            container.Register<MyService>().SetSingletonMode(SingletonMode.Singleton);
        }
}

using TheRealIronDuck.Ducktion.Configurators;
using TheRealIronDuck.Ducktion.Enums;

public class MyMonoConfigurator : MonoDiConfigurator
{
        public void Register(DiContainer container)
        {
            // Mark the service as Singleton
            container.Register<MyService>().Singleton();
            
            // Mark the service as Non Singleton
            container.Register<MyService>().NonSingleton();
            
            // Alias for NonSingleton
            container.Register<MyService>().Transient();
            
            // Specify the singleton mode manually
            container.Register<MyService>().SetSingletonMode(SingletonMode.Singleton);
        }
}

Of course this also works when overriding services.

INFO

Auto Resolved Services have their own default singleton mode, which may differ from the general default mode. This can be configured in the Configuration Documentation.
