حال که پورت هم تنظیم شده است میتوانیم RavenDB را در Worker Role راه بیاندازیم:

public class MyBusiness : BusinessBase<Entity.MyEntity>
    {
        [ImportingConstructor]
        public MyBusiness  ( [Import( typeof( IUnitOfWork ) )] IUnitOfWork unitOfWork )
            : base( unitOfWork )
        {
        }
        public void Add(Entity.MyEntity entity)
        {
            UnitOfWork.Set<MyEntity>().Add(entity);
        }
    }

public class Category : BusinessBase<Entity.Category>
    {      
        [ImportingConstructor]
        public Category( [Import( typeof( IUnitOfWork ) )] IUnitOfWork unitOfWork )
            : base( unitOfWork )
        {
        }

        public override void Add( Entity.Category entity )
        {
            new MyBusiness().Add( new Entity.MyEntity() );
            UnitOfWork.Set<Entity.Category>().Add( entity );
            UnitOfWork.SaveChanges();
        }
    }

در مرحله‌ی بعد سه پکیج زیر را باید نصب کنیم :

- Microsoft.AspNet.Identity.EntityFramework

-   Microsoft.AspNet.Identity.OWIN

-  Microsoft.Owin.Host.SystemWeb

• آشنایی با Code first migrations : قسمت اول و دوم
• وادار کردن EF Code first به ساخت بانک اطلاعاتی پیش از شروع به کار برنامه
• بررسی خطاهای متداول عملیات Migration در حین به روز رسانی پروژه‌های EF Code First
