I notice a lot of questions and articles talking about ajax comet. I also found some links to make it "scalable" since some of those posts talk about how it isn't that scalable with ASP.Net. I'm wondering if Microsoft has a solution they're working on or that is out that addresses an AJAX Comet solution for ASP.Net that is free.
As a side question, I'm wondering this because Microsoft.NET 4.5 talks about WebSockets, which seems to be a "better" solution than AJAX Comet? Or am I wrong on this one and they aren't competing technologies?
