title: chatbot is working for welcome message fine in local bot framework Emulator, but not work in azure chatbot
body: <p>I created one chatbot in Asp.net core using c#, I am facing issue regarding welcome message when the user opens chatbot the first time. it is working fine when I use Microsoft bot framework emulator. but when I create bot service in azure bot option then it is not through a welcome message. but yes, when you type anything and press send button after that it is displayed a welcome message. Means, azure bot receive any message then it responds but I want to display my welcome message first when the user open chat bot panel. any idea what is the solution in it?</p>
  
  <p>i used this code, it is working fine in local bot framework emulator, but not in azure bot. </p>
  
  <pre><code>namespace Microsoft.BotBuilderSamples
  {
      public class DialogAndWelcomeBot&lt;T&gt; : DialogBot&lt;T&gt; where T : Dialog
      {
          public DialogAndWelcomeBot(ConversationState conversationState, UserState userState, T dialog, ILogger&lt;DialogBot&lt;T&gt;&gt; logger)
              : base(conversationState, userState, dialog, logger)
          {
          }
  
          protected override async Task OnMembersAddedAsync(
              IList&lt;ChannelAccount&gt; membersAdded,
              ITurnContext&lt;IConversationUpdateActivity&gt; turnContext,
              CancellationToken cancellationToken)
          {
              foreach (var member in membersAdded)
              {   
                  if (member.Id != turnContext.Activity.Recipient.Id)
                  {   
                      var replyOne = MessageFactory.Text($"Hi there! I'm bot. ");
                      await turnContext.SendActivityAsync(replyOne, cancellationToken);
                      var replyTwo = MessageFactory.Text($"How may i assist you?");
                      await turnContext.SendActivityAsync(replyTwo, cancellationToken);
                  }
              }
          }
      }
  }
