Deleted this sentence: "Since you will be adding the WCF Service to an executable project (the
host) the template will also generate some code for hosting the service."

"Open IHelloIndigoService.cs and..." now reads "Open HelloIndigoService.cs and..."

"Open Program.cs and add code to host the new Main() entry point..." now reads "Open Program.cs and add code to the Main() entry point..."

Deleted this sentence: "Since you will be adding the WCF Service to an executable project (the

"Open IHelloIndigoService.cs and..." now reads "Open HelloIndigoService.cs and..."

"Open Program.cs and add code to host the new Main() entry point..." now reads "Open Program.cs and add code to the Main() entry point..."

The instructions seem to be really messed up:
====================
Rename Service1.cs and HelloIndigoService.cs and Service1.cs to IHelloIndigoService.cs and HelloIndigoService.cs, respectively.

I assmume that the following is what is intended:
====================
Rename IService1.cs and Service1.cs to IHelloIndigoService.cs and HelloIndigoService.cs, respectively.

Note from the Author or Editor:
Page 38, #2 reads:

"Rename Service1.cs and HelloIndigoService.cs and IService1.cs to IHelloIndigoService.cs and HelloIndigoService.cs, respectively."

A previous errata update was obviously poorly applied. It should read:

"Rename Service1.cs and IService1.cs to HelloIndigoService.cs and IHelloIndigoService.cs, respectively."

In the code block, "host=..." host is now in all lower case.

Added the following to end of this paragraph:

Although a rare occurence, it is possible for the ServiceHost to be put into a faulted state. For example,
if there are errors in the service model configuration. If the ServiceHost State property is set to
CommunicationState.Faulted, when Close() is called an exception will be thrown. For this reason, it is best
to check the State property of the ServiceHost instance and call Abort() if it is in a faulted state. This
technique was illustrated in Chapter 1

Note from the Author or Editor:
This is correct in the August 2008 reprint.

"Although a new service instance is allocated for each request with PerCall services, Multiple concurrency
mode is still useful in the case where there is a session to increase throughput for multi-threaded clients.
That's because the lock acquired when the first request is received from a particular client proxy is
actually on the context, not on the service object. When a session is present, this lock prevents more than
one thread from entering the same session - which means the TCP socket, the named pipe, or the reliable or
secure session."

"The release of the .NET Framework 3.5 includes a new feature for WCF - Durable Services. This feature makes
it possible to have an application session for a WCF service persist to a database between calls and be
restored on subsequent calls. This feature relies on the Windows Workflow Foundation persistence services.
This feature does not preserve transport sessions, so the client must still recreate the proxy if a
particular machine is no longer available, or if the session is terminated for some other reason."

"This is a TimeSpan property that controls the duration of the reliable session including channel layer
activity. If no messages, including infrastructure messages such as reliable session acknowledgements, are
transmitted during this elapsed time the session is faulted. The default value is 00:10:00 (or 10 minutes)."
