autofac wcf registration error

问题

I'm trying to attempt a structure with Autofac on Wcf.

    namespace WcfService1.Model
    {
        [DataContract(IsReference = true)]
        public partial class Account
        {
            [DataMember]
            public int Id { get; set; }
            [DataMember]
            public string Name { get; set; }
            [DataMember]
            public string Surname { get; set; }
            [DataMember]
            public string Email { get; set; }
            [DataMember]
            public Nullable<System.DateTime> CreateDate { get; set; }
        }    
    }

Model>IAccounRepository.cs

namespace WcfService1.Model
{
  public interface IAccountRepository
    {
        IEnumerable<Account> GetAllRows();
        bool AddAccount(Account item);
    }
}

Model>AccounRepository.cs

namespace WcfService1.Model
{
    public class AccountRepository:IAccountRepository
    {
        private Database1Entities _context;
        public AccountRepository()
        {
            if(_context == null)
                _context =new Database1Entities();
        }

        public IEnumerable<Account> GetAllRows()
        {
            if (_context == null)
                _context = new Database1Entities();
            return _context.Account.AsEnumerable();
        }        

        public bool AddAccount(Account item)
        {
            try
            {
                if (_context == null)
                    _context = new Database1Entities();
                _context.Entry(item).State = EntityState.Added;
                _context.Account.Add(item);
                _context.SaveChanges();
                return true;
            }
            catch (Exception ex)
            {
                var str = ex.Message;
                return false;
            }
        }
    }
}

DbConnection > EntityFramework + DbContext
IService1.cs

Code:

namespace WcfService1
{
    [ServiceContract(SessionMode = SessionMode.Allowed)]
    public interface IService1
    {
        [OperationContract]
        IList<Account> GetAccounts();

        [OperationContract]
        bool AddAccount(Account item);
    }
}

Service1.cs

Code:

namespace WcfService1
{
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class Service1:IService1
    {
        private readonly IAccountRepository _repository;
        public Service1(IAccountRepository repository)
        {
            _repository = repository;
        }    
        public IList<Account> GetAccounts()
        {   
            var items = _repository.GetAllRows().ToList();
            return items;
        }
        public bool AddAccount(Account item)
        {
            item.CreateDate = DateTime.Now;    
            return _repository.AddAccount(item);
        }
    }
}

Service1.svc

Code:

<%@ ServiceHost Language="C#"
                Debug="true"
                Service="WcfService1.Service1, WcfService1"
                Factory="Autofac.Integration.Wcf.AutofacWebServiceHostFactory, Autofac.Integration.Wcf" %>

Global.asax.cs

Code:

protected void Application_Start(object sender, EventArgs e)
        {
            var builder = new ContainerBuilder();
            builder.RegisterType< AccountRepository>().As< IAccountRepository>();
            builder.RegisterType< Service1 >().As< IService1>();

            AutofacHostFactory.Container = builder.Build();
        }

I'm getting the following error, could not find a solution. What's my wrong.

Error Message :

回答1:

In addition to the other answers, you should make sure you're using the fully-qualified service name in the Service attribute of the ServiceHost element in your .svc file.

For example, instead of:

<%@ ServiceHost Language="C#" Debug="true" Service="MoviesService.MoviesService" CodeBehind="MoviesService.svc.cs" %>

Use:

<%@ ServiceHost Language="C#" Debug="true" Service="MoviesService.MoviesService, MoviesService" CodeBehind="MoviesService.svc.cs" %>

回答2:

You should register the service as self, not as the interface.

builder.RegisterType< Service1 >().AsSelf();

回答3:

Just Register the Service1 Like this builder.RegisterType<Service1>(); instead builder.RegisterType<Service1>().As<IService1>();

回答4:

Give this a try:

var builder = new ContainerBuilder();

builder.Register(c => new AccountRepository()).As<IAccountRepository>();
builder.Register(c => new Service1(c.Resolve<IAccountRepository>())).AsSelf();

AutofacHostFactory.Container = builder.Build();

回答5:

You should not use. `builder.RegisterType< Service1 >().As' but use RegisterType without extension methods 'builder.RegisterType();'

回答6:

For me I was using a Project called 'WCF Service'

This by default gave me a name space called WCF_Service, and a assembly name of 'WCF Service'

None of the fixes worked until that space was removed.
