Quick Start: Invoking a long-lived process using the web service API

The following C# code example invokes a long-lived process named MortgageLoan - Prebuilt. Notice that this process is invoked asynchronously. This quick start contains a user-defined method named GetDataSource that creates XML data that is passed to the process. The XML data is created using a MSXML2.DOMDocument50Class instance. (See Invoking Human-Centric Long-Lived Processes.)
