function Get-VersionPSObject {

.SYNOPSIS
|
|
Parse a function into a semver compatible version object instead of the naive .NET implementation.
|
|
The .NET implementation existed before the semver formalization, so it does not implement all of the same properties/metadata concepts.
|
|
While a third-party library may exist that neatly handles these edge-cases, we do not use those in PowerShell due to availability concerns.
|
|
|
|
.PARAMETER Version
|
|
[string] The value to parse.
