Quick Start (Base64): Retrieving task information using the web service API

The following C# code example retrieves all tasks that are based on a process named MortgageLoan - Prebuilt . The status of each returned task is checked to ensure that it is a completed task. Information such as the name of the user who completed the task is retrieved and displayed.
