Does it always time out?  It may be that the timeout isn't coming from the database but is instead a communications timeout.  Looking at the exception and all inner exceptions may help indicate where the timeout is originating.  If it is a communications timeout, then my first thought would be to check the NotesResult class to be sure it's serializable and defined on both client and server.

Hello IdeaBlade,
I'm currently facing troubles when executing a simple stored procedure that executing from SQLServer manager returns in 1-2 second...calling it from my WPF applicazion takes a lot of time and it goes in timeout (other stored procedure that takes 20-40 seconds run fine)

my call is :

    public void LoadData()
        {
            IsBusy = true;
            CanPrintExport = false;

            _repository.LoadNote(App.LoggedUser.IDIstituto, Date,
                           results =>
                           {
                               ResultList = new BindableCollection<NotesResult>(results.Cast<NotesResult>());

                               CanPrintExport = true;
                               IsBusy = false;
                           },
                                      e => MessageBox.Show(e.Message));

        }

and here's my call to the stored procesure in applicationrepository

   public INotifyCompleted LoadNote(int idIstituto, DateTime date, Action<IEnumerable> onSuccess, Action<Exception> onFail)
        {
            var query = Manager.myStore(idIstituto, date);

            query.CommandTimeout = 60; //this can be 180 ...always got the same problem
          
            var op = query.ExecuteAsync();

            return op.OnComplete(onSuccess, onFail);
        }

The strange thing is that a lot of time elapse between the load button click and the RPC completed on the Sql Server profile to appear..

Thanks
Paolo
