Maintenir une connexion Redis ouverte à l'aide de BookSleeve

Comme je n'ai pas de bonnes réponses, j'ai trouvé cette solution (BTW merci @Simon et @Alex pour vos réponses !).

Je veux le partager avec toute la communauté comme référence. Bien sûr, toute correction sera très appréciée.

using System.Net.Sockets;
using BookSleeve;

namespace Redis

    public sealed class RedisConnectionGateway
    {
        private const string RedisConnectionFailed = "Redis connection failed.";
        private RedisConnection _connection;
        private static volatile RedisConnectionGateway _instance;

        private static object syncLock = new object();
        private static object syncConnectionLock = new object();

        public static RedisConnectionGateway Current
        {
            get
            {
                if (_instance == null)
                {
                    lock (syncLock)
                    {
