Install-PSResourceWithRetry now removes any already-loaded versions of the module from the session before importing the resolved version, so the selected version is the only one loaded (not a side-by-side or runner-preinstalled copy).

…n prerelease-aware Per PR review: use 'Get-Module -Name \ -All | Remove-Module' so every loaded instance (all versions, including nested) is removed before import; and when Prerelease is not requested, exclude prerelease candidates from resolution and add a stable-wins tie-breaker so a prerelease is never selected over a stable of the same base version.

…ore unloading Filter/sort on the PSResourceGet 'Prerelease' string (present on both Install-PSResource and Get-InstalledPSResource output) instead of IsPrerelease; and move the unresolvable-constraint throw before Get-Module|Remove-Module so session state is not mutated when the function is going to fail.

Makes the version selected through the

Install-PSResourceWithRetrynow:Prerelease— when prerelease versions are not requested it never resolves to one, with a stable-wins tie-breaker when a stable and a prerelease share the same base version (uses the PSResourceGetPrereleasestring).Get-Module -Name $Name -All | Remove-Module) so no side-by-side version remains.-RequiredVersion … -Force -Globalso the loaded module is deterministic rather than whatever PowerShell auto-loads fromPSModulePath.Technical Details
