TransactionFlowBindingElementImporter Class

Imports the transaction policy (WS-Policy assertions) of a service endpoint, adds implementing binding elements to the binding on the client, and transaction flow attributes to the appropriate operations on the service’s proxy. This class cannot be inherited.

Namespace:  System.ServiceModel.Channels
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public sealed class TransactionFlowBindingElementImporter : IPolicyImportExtension

The service endpoint must have enabled transaction flow and its methods must flow transactions. The converted policy assertions all adhere to the WS-PolicyAssertions standard.

This class is used mainly by the infrastructure when it builds a proxy for a service that is transaction-flow enabled. Calling the ImportPolicy(MetadataImporter, PolicyConversionContext) method adds a TransactionFlowBindingElement instance to the PolicyConversionContext collection of binding elements. This also adds TransactionFlowAttribute instances, as appropriate, on the Operations collection present in the conversion context’s contract.
