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.

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

public sealed class TransactionFlowBindingElementImporter : IPolicyImportExtension

The TransactionFlowBindingElementImporter type exposes the following members.

Public methodTransactionFlowBindingElementImporterInitializes a new instance of the TransactionFlowBindingElementImporter class.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Explicit interface implemetationPrivate methodIPolicyImportExtension.ImportPolicyImports custom policy assertions and adds implementing binding elements. This method cannot be inherited.

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.
