C# 在本地主机上创建运行空间而不提供runspaceconnectioninfo时，某些PowerShell模块（群集cmdlet）无法加载

请参考以下样本： RunspaceSample（string.Empty）；由于术语“Add-VMToCluster”未被识别为cmdlet的名称而失败。 而RunspaceSample（“localhost”）或RunspaceSample（“somecomputerName”）成功了。任何指针，为什么？包含RunspaceConnectionInfo是否会更改用于执行的powershell版本或RunspaceConfiguration？ 另外，如果使用RunSpaceConnectionInfo和ComputerName=“localhost”创建运行空间，即使在本地计算机上执行powershell脚本，也会对性能产生什么影响

谢谢

public static void RunspaceSample(string computerName)
    {
        Runspace rs;
        if (string.IsNullOrEmpty(computerName))
        {
            rs = RunspaceFactory.CreateRunspace();
        }
        else
        {
            var connectionInfo = new WSManConnectionInfo
            {
                OperationTimeout = 10000,
                OpenTimeout = 10000,
                ComputerName = computerName
            };
            rs = RunspaceFactory.CreateRunspace(connectionInfo);
        }

        rs.Open();
        PowerShell ps = PowerShell.Create();
        ps.Runspace = rs;
        string script = @"$ComputerName = 'somevm'; $null = Add-VMToCluster -Name $ComputerName -VMName $ComputerName -ErrorAction SilentlyContinue -verbose";
        ps.AddScript(script);


        Console.WriteLine("Script: {0}", script);
        Console.WriteLine("------------------------");
        foreach (PSObject result in ps.Invoke())
        {
            Console.WriteLine(result.ToString());
        }

        if (ps.HadErrors)
        {
            var sb = new StringBuilder();
            foreach (var errorRecord in ps.Streams.Error)
            {
                sb.AppendFormat("\nError: {0} CategoryInfo: {1}", errorRecord.Exception.Message, (errorRecord.CategoryInfo != null) ? errorRecord.CategoryInfo.ToString() : string.Empty);
            }

            var errorMessage = sb.ToString();
            Console.WriteLine(errorMessage);
        }
    }
