SignalR Lightning Talk

1. SignalR
Contextualizing Reverse Ajax in a
Postmodernized Web 3.0 Domain Space.

2. What is this and why do I care?
SignalR (github): An asynchronous signaling library for ASP.NET to help build
real-time, multi-user interactive web applications.
SignalR (Nuget): A client and server side library for ASP.NET that provides
messaging and an abstraction over a persistent connection.
Bottom line: A solution dealing with the stateless nature of the web =>
making the web fabric appear to behave in a stateful way.
