NServiceBus.NServiceBus can be configured to use Autofac for dependency injection.
Default Usage
endpointConfiguration.UseContainer<AutofacBuilder>();
Existing Instance
var builder = new ContainerBuilder();
builder.RegisterInstance(new MyService());
var container = builder.Build();
endpointConfiguration.UseContainer<AutofacBuilder>(
customizations: customizations =>
{
customizations.ExistingLifetimeScope(container);
});
As of Autofac 4.2.1, the
ContainerBuilder.Update method is marked as obsolete. In the future, updating the instance passed to NServiceBus may not be possible.DependencyLifecycle Mapping
The DependencyLifecycle map to Autofac in the following way.
| DependencyLifecycle | Autofac Equivalent |
|---|---|
| InstancePerCall | Instance Per Dependency |
| InstancePerUnitOfWork | Instance Per Lifetime Scope |
| SingleInstance | SingleInstance |
