IWsdlImportExtension Interface
Implement and attach to a WsdlImporter object to control how the importer maps Web Services Description Language (WSDL) parts to those of a ServiceDescription object.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
The IWsdlImportExtension type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | BeforeImport | Called prior to importing metadata documents. |
![]() | ImportContract | Called when importing a contract. |
![]() | ImportEndpoint | Called when importing an endpoint. |
Implement the IWsdlImportExtension interface to control the mapping between WSDL and ServiceEndpoint and ContractDescription objects, especially when reading custom WSDL extensions to modify your contract or endpoint information. Then attach your custom IWsdlImportExtension object to a WsdlImporter either programmatically or by using an application configuration file. You can also attach your custom IWsdlImportExtension object to the internal WsdlImporter used by the Service Model Metadata Utility Tool (Svcutil.exe) using an application configuration file.
The ImportContract method is called to import a contract.
Use the BeforeImport method to modify the metadata that is then imported into ServiceEndpoint and ContractDescription objects.
The following code example shows the use of IWsdlImportExtension to add an System.ServiceModel.Description::IServiceContractGenerationExtension and an System.ServiceModel.Description::IOperationContractGenerationExtension (the WsdlDocumentationImporter, in this case) to modify generated client code at the interface and operation level.
public void ImportContract(WsdlImporter importer, WsdlContractConversionContext context) { Console.Write("ImportContract"); // Contract Documentation if (context.WsdlPortType.Documentation != null) { context.Contract.Behaviors.Add(new WsdlDocumentationImporter(context.WsdlPortType.Documentation)); } // Operation Documentation foreach (Operation operation in context.WsdlPortType.Operations) { if (operation.Documentation != null) { OperationDescription operationDescription = context.Contract.Operations.Find(operation.Name); if (operationDescription != null) { operationDescription.Behaviors.Add(new WsdlDocumentationImporter(operation.Documentation)); } } } }
The following code example shows how to configure the client metadata system to use the custom IWsdlImportExtension from an application configuration file.
