```
using System;
using System.Collections.Generic;
using System.Linq;
using QMSAPI;

class Program
{
    static void Main(string[] args)
    {
        try
        {
            // create a QMS API client
            IQMS apiClient = new QMSClient();

            //retrieve a time limited service key
            ServiceKeyClientMessageInspector.ServiceKey = apiClient.GetTimeLimitedServiceKey();

            Guid qvsId = new Guid("e07c145f-7606-4161-b986-b4288650e3b7"); // The originating QVS ID
            String RestartReason;
            if (apiClient.QVSNeedRestart(out RestartReason, qvsId) == true)    //QVS requires restart if DocFolder changed
            {
                Console.WriteLine("QVS will be restarted. Reason: " + RestartReason);
                apiClient.RestartQVS(qvsId);
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("An exception occurred: " + ex.Message);
        }
        // wait for user to press any key
