Service Behavior
 

The [Service Behavior] attribute is used to apply behavior at the service level. It allows you to control things such as: 

• Concurrency
• Throttling
• Transaction
• Session Management
• Thread Behavior

<services>
      <service behaviorConfiguration="DemoAPI.ServiceBehavior"
        name="DemoAPI.Service">
        <endpoint behaviorConfiguration="webBehavior" binding="webHttpBinding"
          contract="DemoAPI.INudgeService" />
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>

This contains the service section where we define the service name the endpoint section what kind of communication we will provide while transfering data from client to server

<behaviors>
      <serviceBehaviors>
        <behavior name="DemoAPI.ServiceBehavior">
          <!-- To avoid disclosing metadata information, 
          set the value below to false before deployment -->
          <serviceMetadata httpGetEnabled="True"/>
          <!-- To receive exception details in faults for debugging purposes, 
          set the value below to true.  Set to false before deployment 
          to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="True" />
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="webBehavior">
          <webHttp defaultOutgoingResponseFormat="Json" />
        </behavior>
      </endpointBehaviors>
    </behaviors>

This is the behaviour section that includes metadata settings which needs to be defined for accessing and viewing properties associated with this service
