Please note that this video was using the first beta version of SignalR, lots of things changes since that day.
In almost a weekend I was able to craft a not so terrible live support solution using SignalR. If you did not try it so far I highly encourage you to check it out. Despite the fact that lots of SignalR demos are related to chat, the possibility are just incredible and even for “non-sexy” line of business data-entry apps.
I’ve published an early alpha preview of the version 2 so you can play with the code and see for yourself how amazing SignalR is.
