How to: Specify One-Way or Request-Response Operations for ASP.NET Web Services
By default, ASP.NET Web service operations are defined as request-response operations. A request-response operation always returns a message to the calling application upon completion, even if the operation returns a void type. However, you can designate the operation as a one-way operation so that the Web server hosting the Web service acknowledges the original request but the operation does not return a response upon completion.
For more information about ASP.NET Web service operations, see Overview of ASP.NET Applications on Application Diagrams.
To specify an ASP.NET Web service operation as a one-way or request-response operation
In the Web Service Details window, right-click the operation icon and choose Properties.
Tip
If the Web Service Details window is closed, right-click the Web service provider endpoint on the application diagram and choose Define Operations.
In the Properties window, set the WSDL One-Way property as follows:
True to specify that the Web server acknowledges the original request but that the operation does not return a response upon completion.
False to specify that the operation returns a response upon completion. (Default)
The operation icon indicates whether the operation is a one-way or request-response operation.
