NServiceBus.NServiceBus can be configured to use Autofac for dependency injection.
Default usage
endpointConfiguration.UseContainer<AutofacBuilder>();
Using an existing container
var builder = new ContainerBuilder();
builder.RegisterInstance(new MyService());
var container = builder.Build();
endpointConfiguration.UseContainer<AutofacBuilder>(
customizations: customizations =>
{
customizations.ExistingLifetimeScope(container);
});
Although it is possible to update the container after passing it to NServiceBus using the
ContainerBuilder.Update method, from Autofac 4.2.1 onwards that method is marked as obsolete. It is recommended not to use this method to update the container after it has been passed to NServiceBus.DependencyLifecycle mapping
DependencyLifecycle maps to Autofac instance scopes as follows:
DependencyLifecycle | Autofac instance scope |
|---|---|
| InstancePerCall | Instance Per Dependency |
| InstancePerUnitOfWork | Instance Per Lifetime Scope |
| SingleInstance | Single Instance |
