title: Using Redis Sentinel from c#
body: <p>I have a master-slave configuration with two slaves and three sentinels. If I try the commands with command-line everything is ok.
  But I have some problems configuring it for C#.
  I am using StackExchange.Redis library. But I don't understand what I should do in order to get/set the keys from the master. Should I manually find the master and then get or set the keys or does it do it autonomously? What is the best way to do it? Each time i want to get/set a key should I check who is the master?
  For now I did only this and I left my the other code as it was with only one master.</p>
  
  <pre><code>private static string ServiceName = "mymaster";
  private static string IP { get { return "127.0.0.1"; } }
  private static int Port = 26379;
  
  public static readonly ConnectionMultiplexer Connection = GetConn();
  public static readonly IServer Server = Connection.GetServer(IP, Port);
  
  public static ConnectionMultiplexer GetConn()
  {
      try
      {
          // create a connection
          var options = new ConfigurationOptions()
          {
              CommandMap = CommandMap.Sentinel,
              EndPoints = { { IP, Port } },
              AllowAdmin = true,
              TieBreaker = "",
              ServiceName = ServiceName,
              SyncTimeout = 5000,
              AbortOnConnectFail = true,
              Ssl = false
          };
          var connection = ConnectionMultiplexer.Connect(options, Console.Out);
          return connection;
      }
      catch (Exception ex)
      {
          ASLog.LogError(ex, 1);
          return null;
      }
  }
  </code></pre>
  
  <p>where I have one of the three sentinels at port 26379. 
  Sorry but I am a bit confused how to use this with C#.</p>
