Json Formatter Overview

The Json formatter simply uses the “out of the box” System.Runtime.Serialization.Json.DataContractJsonSerializer class.

The data contract json formatter can be configured declaratively on the service with the WcfRestContrib.ServiceModel.Description.WebDispatchFormatterConfigurationAttribute and WebDispatchFormatterMimeTypeAttribute:

[WebDispatchFormatterConfiguration("application/json")]
[WebDispatchFormatterMimeType(
    typeof(WcfRestContrib.ServiceModel.Dispatcher.Formatters.DataContractJson), 
    "application/json")]
public class Books : IBooksService {...}

Or in configuration:

<system.serviceModel>
    <extensions>
        <behaviorExtensions>
            <add name="webFormatter" 
                 type="WcfRestContrib.ServiceModel.Configuration.WebDispatchFormatter.ConfigurationBehaviorElement, WcfRestContrib, 
                       Version=x.x.x.x, Culture=neutral, PublicKeyToken=89183999a8dc93b5"/>
        </behaviorExtensions>
    </extensions>
    <serviceBehaviors>
        <behavior name="Rest">
          <webFormatter>
            <formatters defaultMimeType="application/json">
              <formatter mimeTypes="application/json" 
                         type="WcfRestContrib.ServiceModel.Dispatcher.Formatters.DataContractJson, WcfRestContrib"/>
            </formatters>
          </webFormatter>
        </behavior>
    </serviceBehaviors>
</system.serviceModel>

One or more formatters can be defined.

NOTE: The WcfRestContrib.ServiceModel.Web.WebServiceHost allows you to specify configuration based behaviors if you do not want to specify this declaratively. See more about under Declarative Binding & Behavior Overview.
