Powershell: Register-PSSessionConfiguration -PSVersion reports that 7.0 is not a valid version

[miketheitguy]

Steps to reproduce

Register-PSSessionConfiguration -Path ".\ContosoJEA.pssc" -PSVersion 7.0

Expected behavior

Expected to be able to register a PSSession Configuration with a PSVersion of 7.0.

Actual behavior

Register-PSSessionConfiguration: Cannot bind parameter 'PSVersion' to the target. Exception setting "PSVersion": "The value 7.0 is not valid for the PSVersion parameter. The available values are 2.0, 3.0, 4.0, 5.0, 5.1."

Note, if you omit the -PSVersion parameter it will successfully register it as a 7.0 session configuration. So really the issue here is consistency and confusion on the parameter.

Good find; also affects Set-PSSessionConfiguration.

Note that since you should be able to create and modify arbitrary session configurations, this should still be fixed.

For reference #11616

@iSazonov, the linked issue is about what endpoint to connect to _by default_, _from a client's perspective_.

By contrast, this issue is about _manually managing_ endpoint definitions (session configurations) on machines acting as remoting _servers_.

If you opt to do so (you may not have to, given that Enable-PSRemoting creates the current version's endpoints for you with defaults), you should be able to specify any existing PowerShell version.

(It seems to me that the value of -PSVersion is only for _informational_ purposes, right? Even if so, you should be able to specify any of the existing version numbers.)

Therefore, please reopen this issue.

Sorry, this was an accident.
