I can party in real time. Can you?

Yep, I can party in real time

Let’s party in real time!Slide7

Any sufficiently advanced technology

is

indistinguishable from

magic

SignalR Hubs

A hub is a .NET class

that inherits from

Microsoft.AspNet.SignalR.Hub

Since Hubs are called on the client by name, the name can be customized if needed

The Clients property of a Hub class exposes dynamic properties useful for targeting specific clients

Hub classes also have virtual methods useful for responding to connected/disconnected eventsSlide12

Persistent ConnectionsSlide24

Persistent SignalR Connections

Low level

Work on top of transport abstraction

Pass untyped messages using Send() and Broadcast()

Client must parse message and know what to doSlide25

Using SignalR’s

Native .NET Client

DemoSlide28

BackplanesSlide29

Hubs are

server-bound, so you’ll need to use a

backplane

if you’re running a web farmSlide30

How do Backplanes Work?

What does SignalR do without a backplane?
