Hi,
I want to add an AppService and a Repository for Azure and this repository will not access database it just doing somethings on cloud. so, if i added something like this
public interface IBlobAppService : IApplicationService public interface IBlobRepository : IRepository
Will these open a connection to the database? if yes, so how to make the DI working without opening a connection to the database because this service and repository will not access the database.
Thanks,

Hi, When program started, DI framework will collect all instance which IApplicationService implemented. The class inherited from IApplicationService will be used for your purpose. Ex: You have following: IExampleService: IApplicationService ExampleService: IExampleService If you don't call database, it doesn't have any problem. Service layer is separated with database.
Best regards

Hi,
Thank you for replying.
What about IRepository, if i did an interface called IExambleRepository implements IRepositoy will this open a connection to the database?

OK, fine! I will explain for this: First, repository is just for handler for each Table (in my opinions). But you must open connection first. Related to this:http://www.aspnetboilerplate.com/Pages/Documents/Unit-Of-Work If you want to open connection auto, mark method with [UnitOfWork] attribute. If you want to open connection by hand, inject IUnitOfWorkManager and implement by follow: Ex:
public void CreatePerson(CreatePersonInput input) { var person = new Person { Name = input.Name, EmailAddress = input.EmailAddress }; //_unitOfWorkManager.Begin() will open connection using (var unitOfWork = _unitOfWorkManager.Begin()) { _personRepository.Insert(person); _statisticsRepository.IncrementPeopleCount(); unitOfWork.Complete(); } } -

@Hussein, you don't have to implement IRepository or IApplicationService. You can implement ITransientDependency to make DI work, if you just want that. See docs: <a class="postlink" href="http://www.aspnetboilerplate.com/Pages/Documents/Dependency-Injection#DocRegisterDependencies">http://www.aspnetboilerplate.com/Pages/ ... pendencies</a>
