dddlib

Model

To install dddlib, run the following command in the Package Manager Console:

Install-Package dddlib

Create a domain model, for example:

public class Car : dddlib.AggregateRoot
{
    // used for reconstitution only
    protected internal Car()
    {
    }

    public Car(string registration)
    {
        // business logic goes here...
        this.Apply(
            new CarRegistered
            {
                Registration = registration
            });
    }

    [dddlib.NaturalKey]
    public string Registration { get; private set; }

    private void Handle(CarRegistered @event)
    {
        this.Registration = @event.Registration;
    }
}

public class CarRegistered
{
    public string Registration { get; set; }
}

Persistence

To install dddlib.Persistence, run the following command in the Package Manager Console:

Install-Package dddlib.Persistence

Persist the domain model, for example:

// replace with a valid SQL Server connection string
var connectionString = @"Server=someServer;Database=someDatabase;";

var repository =
    new dddlib.Persistence.SqlServer.SqlServerEventStoreRepository(
        connectionString);

var car = new Car("W807ASB");
repository.Save(car);

var sameCar = repository.Load<Car>(car.Registration);

Event Dispatcher

To install dddlib.Persistence.EventDispatcher, run the following command in the Package Manager Console:

Install-Package dddlib.Persistence.EventDispatcher

Dispatch the persisted events, for example:

// replace with a valid SQL Server connection string
var connectionString = @"Server=someServer;Database=someDatabase;";

using (new dddlib.Persistence.EventDispatcher.SqlServer.SqlServerEventDispatcher(
    connectionString,
    (sequenceNumber, @event) =>
    {
        // action to perform upon dispatch...
        Console.WriteLine(
            "{0}: Processed {1}",
            sequenceNumber,
            @event.GetType());
    }))
{
    // some blocking action
    Console.ReadLine();
}
