Invoking Web Services Within Workflows

WF provides several activities that allow you to interact with XML web services during the lifetime

of your workflow-enabled application. When you wish to simply call an existing web service, you

can make use of the InvokeWebService activity. 

■

Note

Given that WCF is the preferred API to build services, this edition of the text does not cover the construc-

tion of XML web services in any great detail (Chapter 25 broached the topic in passing); therefore the web service

we will be calling here is intentionally simple.
