I agree with the first line by ahren that 'That's because the $.ajax() call is asynchronous.'

you could try adding a setting - async:false which is true by default. This makes the call synchronous.

you can edit your code as :

function getMessageCount() {
                var count;
                $.ajax({
                    type: "POST",
                    url: "http://localhost:43390" + "/services/DiscussionWidgetService.asmx/GetMessageCount",
                    dataType: "json",
                    async:false,
                    contentType: "application/json; charset=utf-8",
                    success: function (data) {                            
                        count = data.d;
                    } //success
                });
                return count;
            }
