Top of page: VB Example

There are two mistakes in the VB example of the Enum:

1) The <DataContract()> attribute is omitted, though it's present in the corresponding C# example.
2) The enum's type ("int") is declared in C# notation instead of the VB equivalent.

Currently it reads

'VB
Public Enum TitleOptions : int

It should read

'VB
<DataContract(Namespace := "http://schemas.fabrikam.com/customers/")> _
Public Enum TitleOptions As Integer

While it's true that the XmlSerializer is an Opt-Out serializer, this is not accomplished using the "Serializable" and "NonSerialized" attributes (which are found in the System namespace) Those attributes are only for REGULAR serialization (via SoapFormatter and BinaryFormatter, both in the System.Runtime.Serialization.Formatters namespace).

XML Serialization, using the XmlSerializer, does NOT require any class decoration (see http://msdn.microsoft.com/en-us/library/ms733901.aspx).

To Opt-Out members while using the XmlSerializer, you should use the "XmlIgnore" attribute (in the System.XML.Serialization namespace)

lesson review

In the questions of the lesson review I had two identical questions but with different answers.

QUESTION 53 and 54 in default order.
ANSWERS of 53 seems OK to me. So it difficult to explain why only one of the possible answers fits for question 54. Randomize?

Question no. 2

The configuration element contains an endpoint that is configured to use the behavior element with name "DefaultBehavior". The 'endpointBehaviors' element only contains an element with name "UpdateClient". Therefore, the configured behavior will be ignored by WCF and the endpoint will use the default behavior. This means that the client will not use the 'Identification' impersonationlevel.
The correct answer to the question therefore should be B, E instead of B,D

IN 1st paragraph


It says:

"It is also possible for a single ServiceHost object to expose the same contract on different bindings.
For example, the following code defines a service host that allows requests to arrive
either through TCP or HTTP."

But the c# code example below it uses TWO DIFFERENT CONTRACTS:

ServiceHost host = new ServiceHost(typeof(UpdateService));
host.AddServiceEndpoint(typeof(IUpdateService),
new NetTcpBinding(), "net.tcp://localhost:8000/UpdateService");
host.AddServiceEndpoint(typeof(IRetrieveService),
new WsHttpBinding("http://localhost/UpdateService");

third line from bottom of page

I think this line should read:

<source name="System.ServiceModel.MessageLogging">

instead of:

<source name="System.ServiceModel.MessageLoging">

This appears in the print, pdf and Safari online versions.

middle of the page, just below the first ruled line

I think that the line "MORE INFO Downloading the .NET 5 SDK"

should read:

"MORE INFO Downloading the .NET 3.5 SDK"

only figure on the page

The image on this page is not the diagram the author(s) intended. It's the graphic for the next figure, 6-9, a command line window. The correct image would look more like the previous figure, 6-7, Proxy message pipeline. This error is present in the pdf, print and Safari books online versions but the drop down box is not enabled for multiple selections.

I am planning to present this chapter to the CMAP certification study group, here in Maryland, in about 4 weeks. Is there any way I could be emailed the link to the correct figure? That would be way cool.

TIA,
Kirk

Chapter 8, 2nd paragraph

On page 394 - Chapter 8: User-Level Security. On the 2nd paragraph below the code it mentions: 'customerCertificateValidatorType' - I think this attribute should be instead: 'customCertificateValidatorType'

Lesson 2 - question 1. Under A

On page 575, Answers for Chapter 8: Lesson 2 - question 1. Under A. it mentions:
"A. Incorrect: The User property in the ..."

When I had a look in code, I couldn't find a 'User' property in .NET 4.0. When I looked on the MSDN website for .NET 3.5 it doesn't appear on that either, see:

http://msdn.microsoft.com/en-us/library/system.security.permissions.principalpermissionattribute_properties(VS.90).aspx

I believe the alternative property should be 'Name' instead of 'User' for this answer (on page page 575) - this needs to be confirmed by a developer in Microsoft as detailed below.

Name
Gets or sets the name of the identity associated with the current principal.

Answers C and D

In the answers C and D the IContextBehavior is mentioned. This is a not existing interface. It should be corrected with IContractBehavior. This interface is explained in lesson 2 of chapter 12 within the paragraph about Custom Synchronization.
