Usage

Configuration

Option 1: Use IConfiguration to configure the service bus

// Initialize EventPubSubService
var eventPubSubConfig = builder.Services
                               .AddEventPubSubService()
                                // scan for event messages in the given assembly
                               .AddEventMessagesFromAssemblies(Assembly.GetExecutingAssembly(), typeof(DistributedTestMessage).Assembly)
                                // scan for event handlers in the given assembly
                               .AddEventHandlersFromAssemblies(Assembly.GetExecutingAssembly());

var massTransitConfigurator = eventPubSubConfig.EnableMassTransit();

// Add Azure Service Bus
massTransitConfigurator.UseAzureServiceBus(builder.Configuration);

// this should be called before builder.Build(), or before exiting ConfigureServices method
massTransitConfigurator.Finalize();

In your appsettings.json file, add the the following configuration:

  "ServiceBusConfiguration": {
    "ConnectionString": "<your-endpoint-to-azure-service-bus>",
    "SubscriptionName": "<application-name>",
    "IncludeNamespaceForTopicName": false
  }

Option 2: Configure from code

// Initialize EventPubSubService
var eventPubSubConfig = builder.Services
                               .AddEventPubSubService()
                                // scan for event messages in the given assembly
                               .AddEventMessagesFromAssemblies(Assembly.GetExecutingAssembly(), typeof(DistributedTestMessage).Assembly)
                                // scan for event handlers in the given assembly
                               .AddEventHandlersFromAssemblies(Assembly.GetExecutingAssembly());

var massTransitConfigurator = eventPubSubConfig.EnableMassTransit();

massTransitConfigurator.SetSubscriptionName("<application-name>");
// if you want to exclude namespace in entity name
massTransitConfigurator.ExcludeNamespaceInEntityName();

// Add Azure Service Bus
massTransitConfigurator.UseAzureServiceBus("<azure-connection-string>");

// this should be called before builder.Build(), or before exiting ConfigureServices method
massTransitConfigurator.Finalize();

Refer to the Event PubSub Library, MassTransit Integration Library for more details on how to configure the event messages, request/response messages and how to implement handlers for them.
