Specifies the internal execution behavior of a service contract implementation.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Thetype exposes the following members.
|AddressFilterMode||Gets or sets the AddressFilterMode that is used by the dispatcher to route incoming messages to the correct endpoint.|
|AutomaticSessionShutdown||Specifies whether to automatically close a session when a client closes an output session.|

|GetHashCode||Returns the hash code for this instance. (Inherited from Attribute.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|GetWellKnownSingleton||Retrieves an object that implements the service and that is used as the singleton instance of the service, or a null reference (Nothing in Visual Basic) if there is no singleton instance.|
|IsDefaultAttribute||When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)|
|Match||When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)|
|SetWellKnownSingleton||Specifies an object that implements the service and that is used as the singleton instance of the service.|
|ShouldSerializeConfigurationName||Returns a value that indicates whether the ConfigurationName property has changed from its default value and should be serialized.|
|ShouldSerializeReleaseServiceInstanceOnTransactionComplete||Returns a value that indicates whether the ReleaseServiceInstanceOnTransactionComplete property has changed from its default value and should be serialized.|

|_Attribute.GetIDsOfNames||Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)|
|_Attribute.GetTypeInfo||Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)|
|_Attribute.GetTypeInfoCount||Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)|
|_Attribute.Invoke||Provides access to properties and methods exposed by an object. (Inherited from Attribute.)|
|IServiceBehavior.AddBindingParameters||Passes custom data objects to the bindings that support the behavior properties.|
|IServiceBehavior.ApplyDispatchBehavior||Customizes the service run time to support the behavior properties.|
|IServiceBehavior.Validate||Confirms that the service description and service host are capable of supporting the behavior.|
Apply the attribute to a service implementation to specify service-wide execution behavior. (To specify execution behavior at the method level, use the OperationBehaviorAttribute attribute.) This attribute can be applied only to service implementations. For working examples, see the Service Behaviors Samples.
properties are a Windows Communication Foundation (WCF) programming model feature that enables common features that developers otherwise have to implement. For more information about these and other behaviors, see Specifying Service Run-Time Behavior. For more information about the underlying runtime properties that some of the following properties set, see Extending ServiceHost and the Service Model Layer.
The AddressFilterMode property specifies the type of filter that the dispatcher system uses to locate the endpoint that handles requests.
The AutomaticSessionShutdown property automatically closes the session when the channel is closed and the service has finished processing any remaining messages.
The ConcurrencyMode property controls the internal threading model, enabling support for reentrant or multithreaded services.
The ConfigurationName property is used to declare a name for use in the name attribute of the <service> element in a configuration file.
The IgnoreExtensionDataObject property enables the run time to ignore extra serialization information that is not required to process the message.
The IncludeExceptionDetailInFaults property specifies whether unhandled exceptions in a service are returned as SOAP faults. This is for debugging purposes only.
The InstanceContextMode property specifies whether and when services and their service objects are to be recycled during an exchange with a client.
The MaxItemsInObjectGraph property to limit on the number of items in an object graph that are serialized.
The ReleaseServiceInstanceOnTransactionComplete property specifies whether the service object is recycled when a transaction completes.
The TransactionAutoCompleteOnSessionClose property specifies whether outstanding transactions are completed when the session closes.
The TransactionIsolationLevel property specifies the transaction isolation level that the contract supports.
The TransactionTimeout property specifies the time period within which a transaction must complete or it aborts.
The UseSynchronizationContext property indicates whether to synchronize inbound method calls with the user interface thread automatically.
The ValidateMustUnderstand property informs the system whether it should confirm that SOAP headers marked as MustUnderstand have, in fact, been understood.
The following code example demonstrates the properties. The BehaviorService class uses the attribute to indicate that:
The service object is recycled when the transaction completes.
There is one service object for each session.
The service is single-threaded and does not support reentrant calls.
Furthermore, at the operation level, the OperationBehaviorAttribute values indicate that the TxWork method automatically enlists in flowed transactions or creates a new transaction to do the work, and that the transaction is committed automatically if an unhandled exception does not occur.
The underlying binding must support flowed transactions for the following code example to execute properly. To support flowed transactions using the WSHttpBinding, for example, set the TransactionFlow property to true in code or in an application configuration file. The following code example shows the configuration file for the preceding sample.
<configuration> <system.serviceModel> <services> <service name="Microsoft.WCF.Documentation.BehaviorService" behaviorConfiguration="metadataAndDebugEnabled" > <host> <baseAddresses> <add baseAddress="http://localhost:8080/SampleService"/> </baseAddresses> </host> <!-- Note: This example code uses the WSHttpBinding to support transactions using the WS-AtomicTransactions (WS-AT) protocol. WSHttpBinding is configured to use the protocol, but the protocol is not enabled on some computers. Use the xws_reg -wsat+ command to enable the WS-AtomicTransactions protocol in the MSDTC service. --> <endpoint contract="Microsoft.WCF.Documentation.IBehaviorService" binding="wsHttpBinding" bindingConfiguration="wsHttpBindingWithTXFlow" address="http://localhost:8080/BehaviorService" /> <endpoint contract="Microsoft.WCF.Documentation.IBehaviorService" binding="netTcpBinding" bindingConfiguration="netTcpBindingWithTXFlow" address="net.tcp://localhost:8081/BehaviorService" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="metadataAndDebugEnabled"> <serviceDebug includeExceptionDetailInFaults="true" /> <serviceMetadata httpGetEnabled="true" httpGetUrl="" /> </behavior> </serviceBehaviors> </behaviors> <!-- binding configuration - configures a WSHttpBinding to require transaction flow --> <bindings> <wsHttpBinding> <binding name="wsHttpBindingWithTXFlow" transactionFlow="true" /> </wsHttpBinding> <netTcpBinding> <binding name="netTcpBindingWithTXFlow" transactionFlow="true" /> </netTcpBinding> </bindings> </system.serviceModel> </configuration>
