在不使用dbcontext类的情况下实现owin

Question

所以我为mvc 4项目实现了简单的owin。现在我能够正确地使用appdbcontext类保存和检索用户信息。我的问题是所有其他数据库操作我有wcf服务层，它处理所有数据库调用以保存和检索数据。因此，Web层中不会打开数据库连接。但对于owin，我被迫将连接字符串放在Web层中，并在Web层本身进行db调用。有没有办法让db contxet类将数据发送到我的wcf服务？我的启动类是这个

public class Startup
{
    public static Func<UserManager<AppUser>> UserManagerFactory { get; private set; }
    public static Func<RoleManager<IdentityRole>> rolemanagerfactory { get; private set; }
    public void Configuration(IAppBuilder app)
    {
        app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = "ApplicationCookie",
                LoginPath = new PathString("/Account/Account/Login")
            });

        UserManagerFactory = () =>
        {
            var usermanager = new UserManager<AppUser>(new UserStore<AppUser>(new AppDbContext()));
            usermanager.UserValidator = new UserValidator<AppUser>(usermanager)
           {
              AllowOnlyAlphanumericUserNames = false
           };
            return usermanager;
        };


        rolemanagerfactory = () =>
        {
            var rolemanager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(new AppDbContext()));
            return rolemanager;
        };
    }
}

我给用户管理员的AppUser类就是这个

 public class AppUser :IdentityUser
 {
    public string firstname { get; set; }
    public string lastname { get; set; }
    public string addressline1 { get; set; }
    public string addressline2 { get; set; }
    public string addressline3 { get; set; }
    public string city { get; set; }
    public int citycode { get; set; }
    public string state { get; set; }
    public int statecode { get; set; }
    public string pincode { get; set; }
    public string country { get; set; }
    public int countrycode { get; set; }
    public string mobile { get; set; }
    public string baseGPSLong { get; set; }
    public string baseGPSLat { get; set; }
    public bool IsActive { get; set; }

}

当然appdbcontext类是这个

public class AppDbContext : IdentityDbContext<AppUser>
{
    public AppDbContext()
        : base("CSPL.Epons.Data.Properties.Settings.eponsmasterConnectionString")
    {
    }
}
