184.108.40.206.14 GET_COMMAND_METADATA Message
The syntax of this message is specified in section 220.127.116.11.
The RunspacePool MUST be in an Opened state (section 18.104.22.168.2) when this message is sent. The PowerShell client sends this message to get command metadata from the server. When sending this PowerShell message and receiving responses from the server, the client uses similar data structures that are used for executing a pipeline (section 22.214.171.124).
The PowerShell client constructs a GUID to represent the pipeline, initializes the pipeline state (section 126.96.36.199.2) to Running, constructs the message (section 188.8.131.52), and sends it to the PowerShell server.
For more details on how a PowerShell client gets command metadata from a PowerShell server, see to section 184.108.40.206.
