OperationContractGenerationContext Class

Passed to the IOperationContractGenerationExtension.GenerateOperation method to enable the modification of an operation contract and its context prior to generating code.

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

public class OperationContractGenerationContext

Use the OperationContractGenerationContext object passed to the IOperationContractGenerationExtension.GenerateOperation method to modify the code document object model prior to the generation of code. Typically, the System.ServiceModel.Description.IOperationContractGenerationExtension interface is implemented on a custom System.ServiceModel.Description.IWsdlImportExtension implementation that is used to import custom WSDL elements or otherwise modify the code at the service or operation level. To modify the code at the service level, see System.ServiceModel.Description.IServiceContractGenerationExtension.

The following example shows the use of the OperationContractGenerationContext object passed to the IOperationContractGenerationExtension.GenerateOperation method to add code comments extracted from custom WSDL elements.

public void GenerateOperation(OperationContractGenerationContext context)
  Console.WriteLine("In generate operation.");

The following code example shows the resulting code comments.
