NServiceBus.SimpleInjector

NOTE: Starting with NServiceBus version 8, the dependency injection container adapter packages are no longer required. NServiceBus directly supports the Microsoft.Extensions.DependencyInjection.Abstractions model and third party containers can be integrated using the externally-managed container mode. Visit the dependency injection upgrade guide for further information.

NServiceBus can be configured to use Simple Injector for dependency injection.

Default usage

endpointConfiguration.UseContainer<SimpleInjectorBuilder>();

Using an existing container

var container = new Container();
container.Options.DefaultScopedLifestyle = new AsyncScopedLifestyle();
container.Options.AllowOverridingRegistrations = true;
container.Options.AutoWirePropertiesImplicitly();

container.Register(
    instanceCreator: () =>
    {
        return new MyService
        {
            Property = "Created outside"
        };
    },
    lifestyle: Lifestyle.Scoped);

endpointConfiguration.UseContainer<SimpleInjectorBuilder>(
    customizations =>
    {
        customizations.UseExistingContainer(container);
    });

DependencyLifecycle Mapping

DependencyLifecycle maps to Simple Injector lifestyles as follows:

DependencyLifecycle	Simple Injector lifestyle
InstancePerCall	Transient
InstancePerUnitOfWork	Scoped
SingleInstance	Singleton
