Question

I have a silverlight-enabled WCF-service, of which one method absolutely requires the [STAOperationBehavior] attri......e. I need to access user details (Forms Authentication) for the user, ...... Membership.GetUser() fails while the [STAOperationBehavior] attri......e is applied.

i.e.

    [STAOperationBehavior]
    [OperationContract]
    public string DoWork(int inputStuff)
    {
     Membership.GetUser();//Fails
    }

......

    //NOT ON STA THREAD
    [OperationContract]
    public string DoWork(int inputStuff)
    {
     Membership.GetUser();//Works
    }

我如何利用这一方法获得用户信息,或者以其他方式向用户提供信息?

我最终解决这一问题,删除了STA作业Behavior属地,并手工操作STA的方法:

    //NOT ON STA THREAD
    [OperationContract]
    public void DoWork(int inputStuff)
    {
        //Get the user info while we re not in an STA thread
        var userDetails =  Membership.GetUser();


        System.Threading.Thread thread = new System.Threading.Thread(new System.Threading.ThreadStart(delegate
            {
                //Do STA work in here, using the userDetails obtained earlier
            }));

        thread.SetApartmentState(System.Threading.ApartmentState.STA);
        thread.Start();
        thread.Join();
    }

略微大意,但我没有发现这样做的其他方法。
