Question

I want to send data to a specific client. to do that I am trying with the following;

public Task GetWaitingOrdersCount(string id, string clientId)
    {
        DateTime today = Util.getCurrentDateTime();

      var data = 10

      return Clients.Client(Context.ConnectionId).loadOrders(data);

      //return data;
    }

In the above code, I want to send ‘data’ to the ‘clientId’ passed to this method.
BUT I m having an error in this line

 return Clients.Client(Context.ConnectionId).loadOrders(data);

And the error is

'System.Threading.Tasks.Task<object>' does not contain a definition for 'loadOrders'

the client side code

con.loadOrders = function (data) {
        loadOrders(data);

    };

function loadOrders(data) {

    $('#totalOrders').html(data);
}

Any help about the error???

EDIT:
This is my full client code..

<script type="text/javascript">
var con;
$(document).ready(function () {
    con = $.connection.messagingHub;


    $.connection.hub.start(function () {
        var myClientId = $.connection.hub.id;
        con.getWaitingOrdersCount('<%:ViewBag.rid%>',myClientId).done(function (data) {
            console.log(data);
        });
    });

    con.client.loadOrders = function (data) {
        loadOrders(data);

    };

});
function loadOrders(data) {

    $('#totalOrders').html(data);

I just tried out your code (slightly modified) and it works fine for me. What version of SignalR are you using? Judging by your server code I’d say 1.0Alpha1+ but your client code looks more like 0.5.3, that is unless your con object is assigned to $.connection.yourhub.client;

If you update to SignalR 1.0Alpha2 and change your client code to be:

var con = $.connection.myCon;// This is arbitrary and would change based on your naming

con.client.loadOrders = function (data) {
    loadOrders(data);

};

function loadOrders(data) {
    $('#totalOrders').html(data);
}

That being said I believe your issue has to do with the version of SignalR you are using, server side that is: since you’re receiving a task oriented error. Another piece of information that might be beneficial would be to know how GetWaitingOrdersCount is being called. Aka is it being invoked from the client directly via: con.server.getWaitingOrdersCount or is it being called from within the hub.

Hope this info helps!
