Expose ServiceCollection to MessageBusBuilder.AddAdditionalService

[EtherZa]

Describe the feature

The current implementation of MessageBusBuilder.AddAdditionalService allows for services to be added to the underlying ServiceCollection but it would be useful if an overload with an action that includes direct access to MessageConfiguration/IServiceCollection were added.

Use Case

Access to the underlying service collection and message configuration would greatly improve integration of external extensions eg. transactional outbox pattern

Proposed Solution

public class MessageBusBuilder : IMessageBusBuilder
{
    ...

    private readonly IList<Action<IMessageConfiguration, IServiceCollection>> _additionalServices = new List<Action<IMessagBusBuilder, IServiceCollection>>();

    public IMessageBusBuilder AddAdditionalService(ServiceDescriptor serviceDescriptor)
    {
        _additionalServices.Add((_, services) => services.TryAdd(service));
        return this;
    }

    public IMessageBusBuilder AddAdditionalService(Action<IMessageConfiguration, IServiceCollection> action)
    {
        _additionalServices.Add(action);
        return this;
    }

    internal void Build()
    {
        ...
        foreach (var action in _additionalServices)
        {
            action.Invoke(_messageConfiguration, _serviceCollection);
        }
    }
}
