Starting with NServiceBus version 7, the dependency injection container adapter packages are no longer required. NServiceBus directly supports the Microsoft. model and third party containers can be integrated using the NServiceBus.Extensions.DependencyInjection package or via the .NET Generic Host.
In NServiceBus version 8, NServiceBus will no longer provide adapters for external dependency injection containers.
Visit the dependency injection upgrade guide for further information.
NServiceBus can be configured to use Unity for dependency injection.
Default usage
endpointConfiguration.UseContainer<UnityBuilder>();
Using an existing container
var container = new UnityContainer();
container.RegisterInstance(new MyService());
endpointConfiguration.UseContainer<UnityBuilder>(
customizations: customizations =>
{
customizations.UseExistingContainer(container);
});
DependencyLifecycle mapping
DependencyLifecycle maps to Unity lifetime managers as follows:
DependencyLifecycle | Unity Equivalent |
|---|---|
| InstancePerCall | TransientLifetimeManager |
| InstancePerUnitOfWork | HierarchicalLifetimeManager |
| SingleInstance | ContainerControlledLifetimeManager |
Property Injection
This dependency injection container adapter automatically enables property injection for known types. Use the Func overload of . to get full control over the injected properties if needed.
