How to Configure a WCF-WSHttp Receive Location

You can configure a WCF-WSHttp receive location either programmatically or by using the BizTalk Administration console.

How to Configure a WCF-WSHttp Receive Location Programmatically

The BizTalk Explorer Object Model enables you to create and configure receive locations programmatically. The BizTalk Explorer Object Model exposes theIReceiveLocation receive location configuration interface that has a TransportTypeData read/write property. This property accepts a WCF-WSHttp receive location configuration property bag in the form of a name-value pair of XML strings. To set this property in the BizTalk Explorer Object Model, you must set the InboundTransportLocation property of the IReceiveLocation interface.

The TransportTypeData property of the IReceiveLocation interface does not have to be set. If it is not set, the WCF-WSHttp adapter uses the default values for the WCF-WSHttp receive location configuration as indicated in the following table.

The following table lists the configuration properties that you can set in the BizTalk Explorer Object Model for the WCF-WSHttp receive location.

 

Property name Type Description

Identity

XML Blob

Example:

<identity>

<userPrincipalName value="username@contoso.com" />

</identity>

Specify the identity of the service that this receive location provides. The values that can be specified for the Identity property differ according to the security configuration. These settings enable the client to authenticate this receive location. In the handshake process between the client and service, the Windows Communication Foundation (WCF) infrastructure will ensure that the identity of the expected service matches the values of this element.

The default is an empty string.

OpenTimeout

System.TimeSpan

Specify a time span value that indicates the interval of time provided for a channel open operation to complete.

Default value: 00:01:00

SendTimeout

System.TimeSpan

Specify a time span value that indicates the interval of time provided for a send operation to complete. If you use a request-response receive port, this value specifies a time span for the whole interaction to complete, even if the client returns a large message.

Default value: 00:01:00

CloseTimeout

System.TimeSpan

Specify a time span value that indicates the interval of time provided for a channel close operation to complete.

Default value: 00:01:00

MaxReceivedMessageSize

Integer

Specify the maximum size, in bytes, for a message (including headers) that can be received on the wire. The size of the messages is bounded by the amount of memory allocated for each message. You can use this property to limit exposure to denial of service (DoS) attacks.

Default value: 65536

MessageEncoding

Enum

  • Text - Use a text message encoder.

  • Mtom - Use a Message Transmission Optimization Mechanism 1.0 (MTOM) encoder.

Specify the encoder used to encode the SOAP message.

Default value: Text

TextEncoding

Enum

  • unicodeFFF - Unicode BigEndian encoding.

  • utf-16 - 16-bit encoding.

  • utf-8 - 8-bit encoding

Specify the character set encoding to be used for emitting messages on the binding when the MessageEncoding property is set to Text.

Default value: utf-8

EnableTransaction

Boolean

Specify whether a message is submitted to the MessageBox database using the transaction flowed from clients. If this property is True, the clients are required to submit messages using the WS-AtomicTransaction protocol. If the clients submit messages outside the transactional scope then this receive location returns an exception back to the clients, and no messages are suspended.

The option is available only for one-way receive locations. If the clients submit messages in a transactional context for request-response receive locations, then an exception is returned back to the clients and no messages are suspended.

Default value: False

MaxConcurrentCalls

Integer

Specify the number of concurrent calls to a single service instance. Calls in excess of the limit are queued. The range of this property is from 1 to Int32.MaxValue. Default value: 200

SecurityMode

Enum

  • None

  • Message

  • Transport

  • TransportWithMessageCredential

For more information about the member names for the SecurityMode property, see the Security mode property in WCF-WSHttp Transport Properties Dialog Box, Receive, Security Tab.

Specify the type of security that is used.

Default value: Message

TransportClientCredentialType

Enum

  • None

  • Basic

  • Ntlm

  • Windows

  • Certificate

For more information about the member names for the TransportClientCredentialType property, see the Transport client credential type property in WCF-WSHttp Transport Properties Dialog Box, Receive, Security Tab.

Specify the type of credential to be used when performing the client authentication.

Default value: Windows

MessageClientCredentialType

Enum

  • None

  • Windows

  • UserName

  • Certificate

For more information about the member names for the MessageClientCredentialType property, see the Message client credential type property in WCF-WSHttp Transport Properties Dialog Box, Receive, Security Tab.

Specify the type of credential to be used when performing client authentication using message-based security.

Default value: Windows

AlgorithmSuite

Enum

For more information about the member names for the AlgorithmSuite property, see the Algorithm suite property in WCF-WSHttp Transport Properties Dialog Box, Receive, Security Tab.

Specify the message encryption and key-wrap algorithms. These algorithms map to those specified in the Security Policy Language (WS-SecurityPolicy) specification.

Default value: Basic256

NegotiateServiceCredential

Boolean

Specify whether the service credential is provisioned at the client out of band, or is obtained from the service to the client through a process of negotiation. Such a negotiation is a precursor to the usual message exchange.

If the MessageClientCredentialType property equals None, Username, or Certificate, setting this property to False implies that the service certificate is available at the client out of band and that the client needs to specify the service certificate. This mode is interoperable with SOAP stacks that implement WS-Trust and WS-SecureConversation.

If the MessageClientCredentialType property is set to Windows, setting this property to False specifies Kerberos-based authentication. This means that the client and service must be part of the same Kerberos domain. This mode is interoperable with SOAP stacks that implement the Kerberos token profile (as defined at OASIS WSS TC) as well as WS-Trust and WS-SecureConversation.

When this property is True, it causes a .NET SOAP negotiation that tunnels SPNego exchange over SOAP messages.

Default value: True

EstablishSecurityContext

Boolean

Specify whether the security channel establishes a secure session. A secure session establishes a Security Context Token (SCT) before exchanging the application messages.

Default value: True

ServiceCertificate

String

Specify the thumbprint of the X.509 certificate for this receive location that the clients use to authenticate the service. The certificate to be used for this property must be installed into the My store in the Current User location.

noteNote
You must install the service certificate into the Current User location of the user account for the receive handler hosting this receive location.

The default is an empty string.

UseSSO

Boolean

Specify whether to use Enterprise Single Sign-On (SSO) to retrieve client credentials to issue an SSO ticket. For more information about the security configurations supporting SSO, see the section, "Enterprise Single Sign-On Supportability for the WCF-WSHttp Receive Adapter" in WCF-WSHttp Transport Properties Dialog Box, Receive, Security Tab.

InboundBodyLocation

Enum

  • UseBodyElement - Use the content of the SOAP Body element of an incoming message to create the BizTalk message body part. If the Body element has more than one child element, only the first element becomes the BizTalk message body part.

  • UseEnvelope - Create the BizTalk message body part from the entire SOAP Envelope of an incoming message.

  • UseBodyPath - Use the body path expression in the InboundBodyPathExpression property to create the BizTalk message body part. The body path expression is evaluated against the immediate child element of the SOAP Body element of an incoming message. This property is valid only for solicit-response ports.

For more information about how to use the InboundBodyLocation property, see Specifying the Message Body for the WCF Adapters.

Specify the data selection for the SOAP Body element of incoming WCF messages.

Default value: UseBodyElement

InboundBodyPathExpression

String

For more information about how to use the InboundBodyPathExpression property, see WCF Adapters Property Schema and Properties.

Specify the body path expression to identify a specific part of an incoming message used to create the BizTalk message body part. This body path expression is evaluated against the immediate child element of the SOAP Body node of an incoming message. If this body path expression returns more than one node, only the first node is chosen for the BizTalk message body part. This property is required if the InboundBodyLocation property is set to UseBodyPath.

The default is an empty string.

InboundNodeEncoding

Enum

  • Base64 - Base64 encoding.

  • Hex - Hexadecimal encoding.

  • String - Text encoding - UTF-8.

  • XML - The WCF adapters create the BizTalk message body with the outer XML of the node selected by the body path expression in InboundBodyPathExpression.

Specify the type of encoding that the WCF-WSHttp receive adapter uses to decode the node identified by the body path expression specified in InboundBodyPathExpression. This property is required if the InboundBodyLocation property is set to UseBodyPath.

Default value: XML

OutboundBodyLocation

Enum

  • UseBodyElement - Use the BizTalk message body part to create the content of the SOAP Body element for an outgoing response message.

  • UseTemplate - Use the template supplied in the OutboundXMLTemplate property to create the content of the SOAP Body element for an outgoing response message.

For more information about how to use the OutboundBodyLocation property, see Specifying the Message Body for the WCF Adapters.

Specify the data selection for the SOAP Body element of outgoing WCF messages. This property is valid only for request-response receive locations.

Default value: UseBodyElement

OutboundXMLTemplate

String

For more information about how to use the OutboundXMLTemplate property, see Specifying the Message Body for the WCF Adapters.

Specify the XML-formatted template for the content of the SOAP Body element of an outgoing response message. This property is required if the OutboundBodyLocation property is set to UseTemplate. This property is valid only for request-response receive locations.

The default is an empty string.

SuspendMessageOnFailure

Boolean

Specify whether to suspend the request message that fails inbound processing due to a receive pipeline failure or a routing failure.

Default value: True

IncludeExceptionDetailInFaults

Boolean

Specify whether to include managed exception information in the detail of SOAP faults returned to the client for debugging purposes.

Default: False

How to Configure a WCF-WSHttp Receive Location with the BizTalk Administration Console

You can set WCF-WSHttp receive location adapter variables in the BizTalk Administration console. If properties are not set in the receive location, the default receive handler values set in the BizTalk Administration console are used.
