i just need your opinion or explanation on that question:
can we use socket in chat application in asp.net?
because any chat application can be implemented on couple of ways,so when we say socket we say windows application but no web application,because we have the server and clients.
so is there a way to use socket in web application?
thank you.

You can use JavaScript Web Sockets, but they still are not quite there yet. Otherwise you are stuck with the whole setInterval and AJAX way of doing things.

Yes it is very true about this.There are lots of many other way in order to complete this task.It is very interesting work which you are doing.I have solved many this type of work in past.

thank you very much.
