title.\r\n- [X] Make sure you are able to repro it on the [latest released version](https://github.com/PowerShell/PowerShell/releases)\r\n- [X] Search the existing issues.\r\n- [X] Refer to the [FAQ](https://github.com/PowerShell/PowerShell/blob/master/docs/FAQ.md).\r\n- [X] Refer to [Differences between Windows PowerShell 5.1 and PowerShell](https://docs.microsoft.com/powershell/scripting/whats-new/differences-from-windows-powershell).\r\n\r\n### Steps to reproduce\r\n\r\n```powershell\r\nfunction Test-EnumValidation {\r\n    param(\r\n        [ValidateSet([Microsoft.PowerShell.ExecutionPolicy]::Unrestricted, [Microsoft.PowerShell.ExecutionPolicy]::Undefined)]\r\n        [Microsoft.PowerShell.ExecutionPolicy]$Works,\r\n\r\n        [ValidateRange([Microsoft.PowerShell.ExecutionPolicy]::Unrestricted, [Microsoft.PowerShell.ExecutionPolicy]::Undefined)]\r\n        [Microsoft.PowerShell.ExecutionPolicy]$Fails\r\n    )\r\n}\r\n\r\n\r\n$m = New-Object System.Management.Automation.CommandMetaData (Get-Command Test-EnumValidation)\r\n$s = [System.Management.Automation.ProxyCommand]::Create($m)\r\n\r\n$function:proxy = [scriptblock]::Create($s)\r\n\r\n# fails with .ctor exception\r\nproxy\r\n\r\n# if we check the generated function, we see that `ValidateRange` got unquoted strings as arguments in the proxycommand\r\n$s\r\n\r\n...\r\nparam(\r\n    [ValidateSet('Unrestricted','Undefined')]\r\n    [Microsoft.PowerShell.ExecutionPolicy]\r\n    ${Works},\r\n\r\n    [ValidateRange(Unrestricted,Undefined)]\r\n    [Microsoft.PowerShell.ExecutionPolicy]\r\n    ${Fails})\r\n....\r\n```\r\n\r\n### Expected behavior\r\n\r\n`proxy` should work without errors\r\n\r\n\r\n### Actual behavior\r\n\r\n`proxy` throws MethodException due to missing overload.\r\n\r\n\r\n### Error
