However, even though the runspace separates the hosting application from the pipeline execution, communications between the hosting application user and the underlying pipeline execution may occur in two ways. First, the execution may return results that may be displayed by the hosting application. Second, the elements of the pipeline may communicate directly with the host through one of two optional host interfaces that can be specified when the runspace is configured.

Runspaces are created using the RunspaceFactory class provided by the System.Management.Automation.Runspaces namespace. This class provides a single, overloaded CreateRunspace method that returns a Runspace object, which in turn is used to create the Windows PowerShell host and Windows PowerShell pipeline.

Here is the code typically used to create and open a runspace.

Runspace myRunSpace = RunspaceFactory.CreateRunspace(config);
myRunSpace.Open();

For an example of creating runspaces, see How to Create a Windows PowerShell Hosting Application in the Windows PowerShell Programmer's Guide.

For an example of implementing host interfaces, see Creating Applications that Use a Custom Host in the Windows PowerShell Programmer's Guide.
