NServiceBus.MSDependencyInjection

Support for the Microsoft.Extensions.DependencyInjection container.

Usage

public void ConfigureServices(IServiceCollection services)
{
    // register any services to IServiceCollection
    // ...

    var endpointConfiguration = new EndpointConfiguration("Sample.Core");
    endpointConfiguration.UseTransport<LearningTransport>();
    endpointConfiguration.UseContainer<ServicesBuilder>(customizations =>
        {
            customizations.ExistingServices(services);
        });

    endpoint = Endpoint.Start(endpointConfiguration).GetAwaiter().GetResult();
}

To share the used service provide across (ASP) .NET Core and NServiceBus (recommended) you need to return the created service provider.

public IServiceProvider ConfigureServices(IServiceCollection services)
{
    // register any services to IServiceCollection
    // ...

    var endpointConfiguration = new EndpointConfiguration("Sample.Core");
    endpointConfiguration.UseTransport<LearningTransport>();

    UpdateableServiceProvider container = null;
    endpointConfiguration.UseContainer<ServicesBuilder>(customizations =>
        {
            customizations.ExistingServices(services);
            customizations.ServiceProviderFactory(sc => 
            {
                container = new UpdateableServiceProvider(sc);
                return container;
            });
        });

    endpoint = Endpoint.Start(endpointConfiguration).GetAwaiter().GetResult();

    return container;
}

If you need to register the IEndpointInstance also to the service collection please use following pattern:

public IServiceProvider ConfigureServices(IServiceCollection services)
{
    ...
    IEndpointInstance endpointInstance = null;

    services.AddSingleton<IMessageSession>(sp => endpointInstance);

    endpointConfiguration.UseContainer<ServicesBuilder>(c => c.ExistingServices(services));

    endpointInstance = Endpoint.Start(endpointConfiguration).GetAwaiter().GetResult();
}
