PR Summary

PowerShell serialization has a list of known PowerShell types. When an object is deserialized containing a known type it tries to deserialize the object to that specific type and throws exception if it can't succeed. SemanticVersion only exists in PSCore6 so when remoting from Windows PowerShell or importing clixml generated from PSCore6 that contains SemanticVersion, it fails.

It seems to be not in line with the PowerShell Committee's conclusion in #6448.

@iSazonov you are correct, that committee decision was based on an incorrect hypothesis.

LGTM. This is probably the cleanest way to deal with this issue 🎉

One drawback: when PowerShell Core talks to PowerShell Core, the client side won't have a full-fledged SemanticVersion object deserialized back. So potentially this is a breaking change.

Strike my previous comment. It will be deserailzied to a PSObject with all properties from the SemanticVersion object populated. Problem solved, perfectly!

Given it will come back as Deseriealized.System.Management.Automation.SemanticVersion (PSObject) in both Windows PowerShell and PowerShell Core, feels like the right fix.
