Acknowledgments Errata & book support We want to hear from you Stay in touch

1. Internet, asynchrony, multiuser…wow! 2. HTTP: You are the client, and you are the boss

HTTP operations Polling: The answer? Push: The server takes the initiative

WebSockets Server-Sent Events (API Event Source) Push today

Long polling Forever frame

The world needs more than just push

3. Introducing SignalR

What does SignalR offer? Two levels of abstraction Supported platforms OWIN and Katana: The new kids on the block Installing SignalR

4. Persistent connections

Implementation on the server side

Mapping and configuring persistent connections Events of a persistent connection Sending messages to clients Asynchronous event processing Connection groups The OWIN startup class

Implementation on the client side

Initiating the connection by using the JavaScript client Support for older browsers Support for cross-domain connections Sending messages Receiving messages Sending additional information to the server Other events available at the client

Transport negotiation Adjusting SignalR configuration parameters Complete example: Tracking visitors

Project creation and setup Implementation on the client side

HTML markup (tracking.html) Scripts (Scripts/Tracking.js)

Implementation on the server side

Persistent connection (TrackerConnection.cs) Startup code (Startup.cs)

5. Hubs

Server implementation

Hub registration and configuration Creating hubs Receiving messages Sending messages to clients Sending messages to specific users State maintenance Accessing information about the request context Notification of connections and disconnections Managing groups Maintaining state at the server

Client implementation

JavaScript clients Generating the proxy Manual generation of JavaScript proxies Establishing the connection Sending messages to the server Sending additional information Receiving messages sent from the server Logging State maintenance Implementing the client without a proxy

Establishing the connection Invoking server methods State maintenance Receiving messages sent from the server

Complete example: Shared drawing board

Project creation and setup Implementation on the client side

HTML markup (drawingboard.html) Scripts (Scripts/DrawingBoard.js)

Implementation on the server side

Hub (DrawingBoard.cs) Startup code (Startup.cs)

6. Persistent connections and hubs from other threads

Access from other threads

External access using persistent connections Complete example: Monitoring connections at the server Project creation and setup Implementing the website

Page markup (default.aspx) Code-behind (default.aspx.cs)

System for tracing requests (server side)

Persistent connection (ConnectionSpy.cs) Startup code (Startup.cs) Application global class (Global.asax.cs) Optional changes in configuration (web.config)

System for tracing requests (client side)

Spying page (spy.html)

External access using hubs

Complete example: Progress bar Project creation and setup Implementation on the client side

HTML markup (progress.html) Styles (Styles/ProgressBar.css) Script (Scripts/ProgressBar.js)

Implementation on the server side

Hub Expensive process (HardProcess.Aspx) Startup code (startup.cs)

7. Real-time multiplatform applications

Multiplatform SignalR servers

SignalR hosting in non-web applications

Hosting in a console application SignalR in a Windows service

SignalR hosting in platforms other than Windows

Multiplatform SignalR clients

Accessing services from .NET non-web clients

Creating and opening a persistent connection Sending and receiving data using persistent connections Creating and opening connections to hubs Communication with the server using hubs Logging Example: Console application Example: Windows 8/Windows 8.1 application with C#/XAML Project creation and setup MainPage.xaml MainPage.xaml.cs Windows Phone 8 clients

Consumption of services from other platforms

8. Deploying and scaling SignalR

Growing pains Scalability in SignalR Scaling on backplanes

Windows Azure Service Bus

Configuring the service Activating the backplane

SQL Server

Configuring the database Activating the backplane

Redis

Installing Redis Activating the backplane

Custom backplanes Improving performance in SignalR services

Server configuration Monitoring performance

Connection activity Errors Activity in the messaging bus Scale-out providers Other useful performance counters

9. Advanced topics

Authorization in SignalR

Access control in persistent connections Access control in hubs Client authentication

An extensible framework Dependency Injection

Manual dependency injection Releasing dependencies Inversion of Control containers

SignalR with Unity SignalR with Ninject

Unit testing with SignalR

Unit testing of hubs Unit testing persistent connections

Intercepting messages in hubs Integration with other frameworks

Web API ASP.NET MVC Knockout AngularJS
