#Obvs.MessageDispatcher.Autofac
Provides integration support between the core Obvs.MessageDispatcher framework and the Autofac dependency injection framework in the form
of an IMessageHandlerSelector implementation which resolves instances of IMessageHandler<TMessage> from a specified Autofac container.
##Basic configuration Configuration of this integration would look like this:
// Configure and create an Obvs service bus instance
var myObvsServiceBusConfiguration = ConfigureServiceBus();
var serviceBus = myServiceBusConfiguration.CreateServiceBus();
IContainer myAutofacContainer = BuildAutofacContainer();
// Create a message dispatcher for the events that are coming off the service bus
var dispatcherConfiguration = serviceBus.CreateMessageDispatcherFor(sb => sb.Events);
// Configure the dispatcher to use the IMessageHandlerSelector factory which will
// resolve IMessageHandler<TMessage> instances from the supplied Autofac container
dispatcherConfiguration.WithAutofacMessageHandlerSelectorFactory(myAutofacContainer);
// Start the message dispatcher
dispatcherConfiguration.DispatchMessages();##Autofac Integration Details
###Configuration Extensions
This library also contains an extension method for Autofac's ContainerBuilder to help register any instances of IMessageHandler<TMessage> found in any specified assemblies:
var containerBuilder = new ContainerBuilder();
containerBuilder.RegisterMessageHandlers(typeof(MyProgram).Assembly);###Lifetime Scopes
The WithAutofacMessageHandlerSelector extension method provides a factory method which begins a new Autofac lifetime scope by calling
IContainer::BeginLifetimeScope on the supplied IContainer instance.
