This seems a simple C# error. Are you injecting user repository into your constructor? See DI document: <a class="postlink" href="http://www.aspnetboilerplate.com/Pages/Documents/Dependency-Injection#DocResolveConstAndProp">http://www.aspnetboilerplate.com/Pages/ ... nstAndProp</a>

thanks....
how can call the class (the class constructure need 1 argument) public class PersonAppService : IPersonAppService { private readonly IRepository<Person> _personRepository;
public PersonAppService(IRepository<Person> personRepository) { _personRepository = personRepository; } public void CreatePerson(CreatePersonInput input) { person = new Person { Name = input.Name, EmailAddress = input.EmailAddress }; _personRepository.Insert(person); }}

You will not create the class directly. You will use dependency injection. If you are new, I suggest you to start from this document: <a class="postlink" href="http://www.codeproject.com/Articles/791740/Using-AngularJs-ASP-NET-MVC-Web-API-and-EntityFram">http://www.codeproject.com/Articles/791 ...
