2.2.2.13 APPLICATION_PRIVATE_DATA Message

  • Article

The Data field of a PSRP message specifies an APPLICATION_PRIVATE_DATA message when the MessageType field has a value of 0x00021009.

In messages of this type, the Data field is UTF-8 encoded XML, equivalent to the XML created by serializing a Complex Object (section 2.2.5.2) with the following extended properties (see section 2.2.5.2.9). Note that the PowerShell Remoting Protocol does not generate or interpret any application private data; it merely provides a mechanism for the higher layer on the server to send application private data to a client, and a mechanism for the higher-layer on the client to be notified when application private data is reported by the server.

  • Application private data that the higher layer provides to the server when a RunspacePool is created on the server. The PowerShell Remoting Protocol does not interpret this data; it merely passes it to the higher-layers on the client.

    • Property name: ApplicationPrivateData

    • Property type: A Primitive Dictionary (see section 2.2.3.18) or Null Value (see section 2.2.5.1.20).

The Complex Object described in this section SHOULD have no associated type names (section 2.2.5.2.3).
