We have a server written in other technology (not .NET) which supports push technology (basically, can withstand long polling via HTTP 1.1) on the web. We are creating a .NET 3.5 application which is supposed to get push notifications (like a chat) from server when certain event occurs.
Is there any .NET framework for .NET 3.5 or below which works as a client for a HTTP 1.1 pushing? It should support reconnect on getting a message as far as I understand as well as reconnect every two minutes. Can WCF solve this type of tasks?
WCF does support HTTP 1.1 and there is an async way of receiving notifications described with example here.
