c# - First arbitrary messages in signalR has no messageID? -

i wrote simple code --when connected , should yield

• "first !"
• "welcome"
• 3 messages ( timer)

this code :

int = 0; protected override task onconnected(irequest request, string connectionid) {      //first message     connection.send(connectionid, "first !"); //first message      //last messages     timer _timer = new timer(runme, new    {con = connectionid, req = request}, 2000, 1000);          //second message     return connection.send(connectionid, "welcome!"); //second message   }  void runme(dynamic state) {     if (i < 3)     {         connection.send((string) state.con, "loop " + i);         i++;     } } 

and here js code ( inside document.ready block) :

...

connection.received(function (data)         {          $('#messages').append('<li><b>data received = </b>' + data +                                   "<b>connectionid =</b> " + connection.id +                                    '<b>messageid = </b>' + connection.messageid + '</li>');     }); 

i responses.

but if press f5(refresh) -- these typical responses :

refresh again ,

it seems first message never gets messageid :

and later messages sometimes messageid , sometimes not.

ps

i thought myself , maybe it's initialization speed problems , tried :

and again , response :

• what's going on here ? why first messages doesn't messageid ? how can fix ?

in signalr 1.1, connection.messageid set after of connection.received handlers have been called batch of messages.

message ids meant used signalr internally, in signalr 2.0 connection.messageid set before connection.received handlers called.
