7.1. Calling a Web Service Asynchronously
Depending on the speed of your Internet connection, you may have noticed that the Web service client applications you constructed earlier in Step by Step 7.1, “freeze” when you invoke the Web service. That's because by default these applications use synchronous methods to communicate with the Web service, waiting for the SOAP response before allowing any other code to execute. But the proxy classes constructed by .NET include asynchronous methods as well. In this exercise, you'll learn how to call a Web service asynchronously.
