RunspaceFactory.CreateRunspacePool Method (Int32, Int32, RunspaceConnectionInfo, PSHost, TypeTable)


Updated: April 27, 2016

Applies To: Windows PowerShell

Creates a runspace pool that contains runspaces that can be opened on a remote computer. The runspace pool specifies the minimum number of runspaces that Windows PowerShell maintains open, the maximum number of runspaces in the pool, a custom host, connection information, and type table information used for serialization. This method is introduced in Windows PowerShell 2.0.

Namespace:   System.Management.Automation.Runspaces
Assembly:  System.Management.Automation (in System.Management.Automation.dll)

public static RunspacePool CreateRunspacePool(
	int minRunspaces,
	int maxRunspaces,
	RunspaceConnectionInfo connectionInfo,
	PSHost host,
	TypeTable typeTable


Type: System.Int32

The minimum number of opened runspaces that Windows PowerShell maintains open even if the runspaces are no longer needed (default is one). Typically, Windows PowerShell destroys opened runspaces when they are no longer needed.

Type: System.Int32

The maximum number of runspaces that are allowed to be open. Set to a value greater than the minRunspaces parameter.

Type: System.Management.Automation.Runspaces.RunspaceConnectionInfo

An object that derives from the RunspaceConnectionInfo abstract class. This object defines the information used to connect to a specific computer.

Type: System.Management.Automation.Host.PSHost

A PSHost object that represents the host. A host is needed to interact or communicate directly with the user through prompting.

Type: System.Management.Automation.Runspaces.TypeTable

A TypeTable object that contains information used to serialize and deserialize objects passed between computers.

Return Value

Type: System.Management.Automation.Runspaces.RunspacePool

Returns a RunspacePool object that represents the pool with the maximum number of runspaces, the minimum number of runspaces maintained open, and the specified connection information, custom host, and type table used when a runspace from the pool is open.

A runspace pool is a set of runspaces that have the same features, such as the same host, initial session state, and connection information. A runspace from the pool is the operating environment used when invoking the commands of a pipeline. After the runspace pool is created, a runspace from the pool must be opened by using one of the following methods before it can be used:

  • To open a runspace from the pool synchronously, call the Open method.

  • To open a runspace from the pool asynchronously, call the BeginOpen method.
