title: How to remove (not to hide) ReplyKeyboardMarkup in Telegram.Bot using C#?
body: <p>I'm using <strong>Telegram.Bot</strong> library in C# for developing telegram bots.</p>
  
  <p>I post a text message using SendTextMessageAsync() method and sent a Keyboard with it :</p>
  
  <pre><code>bot.SendTextMessageAsync(chatId, "sample msg", ParseMode.Default, false, false, 0, new InlineKeyboardMarkup(keyboardData));
  </code></pre>
  
  <p>I want to remove (not to hide) the keyboard, after click of any user on one of the keyboard buttons, so I use this instruction :</p>
  
  <pre><code>int msgId = bot.SendTextMessageAsync(chatId, "sample msg", ParseMode.Default, false, false, 0, new InlineKeyboardMarkup(keyboardData)).Result;
  ...
  bot.EditMessageReplyMarkupAsync(chatId, msgId, new ReplyKeyboardRemove());
  </code></pre>
  
  <p>But it doesn't work. Please help me about it.</p>
  
  <p>Meanwhile if I set oneTimeKeyboard to true in ReplyKeyboardMarkup, the keyboard will be hide after user click, but it doesn't removed, only it will be hide and user can make it visible using keyboard button of telegram.</p>
