            .RegisterModule(typeof(UserInitializationModule));
    }
}

public class UserInitializationModule : IHttpModule
{
    private static bool initialized;
    private static object lockObject = new object();

    private const string _username = "Owner";
    private const string _password = "p@ssword123";
    private const string _role = "Administrator";

    void IHttpModule.Init(HttpApplication context)
    {
        lock (lockObject)

                if (!WebSecurity.UserExists(_username))
                    WebSecurity.CreateUserAndAccount(_username, _password);

                if (!Roles.RoleExists(_role))
                    Roles.CreateRole(_role);

            }
            initialized = true;
        }
    }

    void IHttpModule.Dispose() { }
