Specifies whether transaction batching is supported for receive operations.

<configuration>
  <system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior>
          <transactedBatching>

Syntax

<transactedBatching maxBatchSize="Integer" />

Attributes and Elements

The following sections describe attributes, child elements, and parent elements.

Attributes

Attribute	Description
`maxBatchSize`	An integer that specifies the maximum number of receive operations that can be batched together in one transaction. The default is 0.

Child Elements

None.

Parent Elements

Element	Description
<behavior>	Specifies an endpoint behavior.

Remarks

A transport that is configured with transaction batching attempts to batch several receive operations into one transaction. By doing so, the relatively high cost of creating a transaction and committing it in every receive operation is avoided.

Example

The following example shows how to add the transacted batching behavior to a service in a configuration file.

<system.serviceModel>
  <services>
    <service name="Microsoft.ServiceModel.Samples.CalculatorService"
             behaviorConfiguration="CalculatorServiceBehavior">
      <host>
        <baseAddresses>
          <add baseAddress="http://localhost:8000/ServiceModelSamples/service" />
        </baseAddresses>
      </host>
      <!-- Define NetMsmqEndpoint -->
      <endpoint address="net.msmq://localhost/private/ServiceModelSamples"
                binding="netMsmqBinding"
                contract="Microsoft.ServiceModel.Samples.IQueueCalculator" />
      <!-- the mex endpoint is exposed at http://localhost:8000/ServiceModelSamples/service/mex -->
      <endpoint address="mex"
                binding="mexHttpBinding"
                contract="IMetadataExchange" />
    </service>
  </services>
  <behaviors>
    <endpointBehaviors>
      <behavior name="endpointBehavior">
        <transactedBatching maxBatchSize="10" />
      </behavior>
    </endpointBehaviors>
    <serviceBehaviors>
      <behavior name="CalculatorServiceBehavior">
        <serviceMetadata httpGetEnabled="true" />
      </behavior>
    </serviceBehaviors>
  </behaviors>
</system.serviceModel>
