In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "There is also a corresponding WebInvokeAttribute for a HTTP POST request."

A block of code is set as follows:

[ServiceContract]
public interface IDataService
{
   [OperationContract]
   string GetData();
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

[ServiceContract(Namespace="WCF.REST")]
public interface IDataService
{
   [OperationContract]
 [WebGet(ResponseFormat= WebMessageFormat.Json)]
   SimpleData GetData();
}

Any command-line input or output is written as follows:

certmgr -c -r localmachine -s my

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Selecting Add Service Reference will launch a dialog where one can control the configuration options on how the WCF service proxy gets generated".
