unit-of-work

I'm creating my first N-Tier MVC application and I've run into a road block with how to manage multiple DbContexts with my database first approach. I have the following layers Presentation Service (WCF) Business Data Access I don't want an entity framework reference in my service layer but I don't see how to create an Interface or something to manage two contexts. I have it working with a single context warpped in a IDatabaseFactory but I can't seem to find an approach to manage two. Below is my UnitOfWork that is created in my Service ctor but every way I look at it I'm still tied to the

Three entities are involved here: Deployment , DeploymentStep , and DeploymentStatusLog . I'll start by pasting the relevant definitions of those classes src/My/Bundle/Entity/Deployment.php <?php namespace My\Bundle\Entity; use Doctrine\ORM\Mapping as ORM; use Doctrine\Common\Collections\ArrayCollection; use Doctrine\ORM\PersistentCollection; /** * @ORM\Table(name="deployment") * @ORM\Entity() */ class Deployment { /** * Status Log Entries for this deployment * * @var \Doctrine\ORM\PersistentCollection * * @ORM\OneToMany(targetEntity="DeploymentStatusLog", mappedBy="deployment", cascade={

I am using EF Core 1.0 (previously known ad EF7) and ASP.NET Core 1.0 (previously known as ASP.NET 5) for a RESTful API. I'd like to have some unit of work scoped to an http request in such a way that when responding to the HTTP request either ALL the changes made to the DbContext will be saved onto the database, or none will be saved (if there was some exception, for example). In the past I have used WebAPI2 for this purpose with NHibernate by using an Action filter where I begin the transaction on action executing, and on action executed I end the transaction and close the session. This was

I have UnitofWork class and it implement IUnitOfWork. I try to register that with autofac : var builder = new ContainerBuilder(); builder .RegisterGeneric(typeof(UnitOfWork<Repository<>,>)) .As(typeof(IUnitOfWork)) .InstancePerDependency(); Implementation is: public class UnitOfWork<T, O> : IUnitOfWork where T : Repository<O> where O : BaseEntity { } public interface IUnitOfWork : IDisposable { void SaveChanges(); } Gives an error "Type expected" but this one work on another project: public class Repository<T> : GenericRepository<T> where T : BaseEntity { public Repository(IDbContext context)

This is the first time I am implementing a more domain-driven design approach. I have decided to try the Onion Architecture as it focuses on the domain rather than on infrastructure/platforms/etc. In order to abstract away from Entity Framework, I have created a generic repository with a Unit of Work implementation. The IRepository<T> and IUnitOfWork interfaces: public interface IRepository<T> { void Add(T item); void Remove(T item); IQueryable<T> Query(); } public interface IUnitOfWork : IDisposable { void SaveChanges(); } Entity Framework implementations of IRepository<T> and IUnitOfWork :
