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