Errata

The author says "On the client side, the service contract can still be represented as an interface (the client only requires metadata) but the name of that interface (the service contract) must match the new service contract name, HelloIndigoService?instead of IHelloIndigoService."

But this has actually not been changed in the example 1-4:

// Client Project - ServiceProxy.cs
[ServiceContract(Name="HelloIndigoService",
Namespace = "http://www.thatindigogirl.com/samples/2006/06")]
public interface IHelloIndigoService
{
[OperationContract]
string HelloIndigo();
}


It Should be

// Client Project - ServiceProxy.cs
[ServiceContract(Name="HelloIndigoService",
Namespace = "http://www.thatindigogirl.com/samples/2006/06")]
public interface HelloIndigoService
{
[OperationContract]
string HelloIndigo();
}

Reads

"It also includes a smaple data contract (to be discussed in Chapter 2."

Should read

"It also includes a sample data contract (to be discussed in Chapter 2"

Step 5.Compile and run the host will not work yet, unless you comment out some lines as follows:

static void Main(string[] args)
{
//using (ServiceHost host = new ServiceHost(typeof(HelloIndigo.HelloIndigoService),
// new Uri("http://localhost:8000/HelloIndigo")))
//{
// host.AddServiceEndpoint(typeof(HelloIndigo.HelloIndigoService),
// new BasicHttpBinding(),
// "HelloIndigoService");
// host.Open();
Console.WriteLine("Press <ENTER> to terminate the service host");
Console.ReadLine();
//}
}

Besides:

host.AddServiceEndpoint(typeof(HelloIndigo.IHelloIndigoService),
new BasicHttpBinding(),
"HelloIndigoService");

Should be:

host.AddServiceEndpoint(typeof(HelloIndigo.HelloIndigoService),
new BasicHttpBinding(),
"HelloIndigoService");

In the code example that ends at the top of page 33, it shows:

Console.WriteLine("Press <ENTER> to terminate the host application");
Console.ReadLine();
{ // this brace is backwards
}
}

It should be:

Console.WriteLine("Press <ENTER> to terminate the host application");
Console.ReadLine();
}
}
}

Under the "Caution/Warning" note, there is an example of what your command/path should look like if the path has spaces. It shows (part of the command):

svcutil /d:"c\Learning WCF\Labs\Chapter1\HelloIndigo\Client"

it is missing a ":". It should read as follows:

svcutil /d:"c:\Learning WCF\Labs\Chapter1\HelloIndigo\Client"

Minor typo: "To host services belonging to a class library project you can either use the WCF Service Host create a separate host project for the service."

It appears "or" should be inserted before "create".

"...is still useful for automating how proxies and service contracts generated..."

Think you're missing the word "are" before "generated".

effect instead of affect:

Original text:
Different behaviors are available to clients and services,since the local affect on the service model also differs.

Should be:
Different behaviors are available to clients and services,since the local effect on the service model also differs.

domain for the type listed as shemas.datacontract.org where it should be schemas.datacontract.org

"You can also use the ContactNamespaceAttribute to automatically..."

That should be "ContractNamespaceAttribute".

top of page 168:

"In this lab, *you'll exposed* web service endpoints....."

Future and past tense in the same phrase.

// During intialization

should read

// During initialization

"This is a problematic for machines....."

I think the "a" is extraneous there.....

"...duplex communication over NetTpcBinding and..."

should be "NetTcpBinding" right?

In all these errors I've been reporting, I'm using the printed version that has
[LSI] and [2011-02-07]
at the bottom of the colophon page....
but I'm starting to wonder if there isn't some kind of pagination discrepancy happening here, relative to the reported errors...I see that there's one reported as being on page 211, the same thing I came to report: "the" misspelled as "teh" in the 4th line of step 2 of the lab. However, since I supposedly have the newest printing, and the errata report a very similar error was already fixed, but on page 211, not 214....and besides if it's really the same error, it HASN'T been fixed. Confusion reigns I guess.

2011--02-07 reprint

"the callback return simply reaquires the lock"

should be "reacquires"...

(wow don't you have the capability of simply running a spell check on the electronic manuscript to avoid typos?)

"yeild" should be "yield"

"Advanced dettings" !?

I guess you mean "Advanced settings" unless "detting" is some new WCF concept I don't understand yet.....

"used" is misspelled here as "ussed"

line 12: <behavior name = "serviceBehavior" [>]
Shouldn't there be a closing "forward slash" for this line?
