Place Data on Orchestrator Data Bus from PowerShell

Q: How can I place data on the System Center Orchestrator data bus from a Windows PowerShell script within Orchestrator?

A: Most built-in activities in Orchestrator automatically publish data to the data bus that can be used by subsequent activities. However, PowerShell scripts running in a Run .Net Script activity don't automatically publish any variables created within the PowerShell. To publish variable content to the data bus from a PowerShell script, the Run .Net Script activity has to be configured to publish specific variables to the databus.
