        }
         else if (message.Type == ActivityTypes.ConversationUpdate)
        {
            // Handle conversation state changes, like members being added and removed
            // Use Activity.MembersAdded and Activity.MembersRemoved and Activity.Action for info
            // Not available in all channels
            IConversationUpdateActivity iConversationUpdated = message as IConversationUpdateActivity;
            if (iConversationUpdated != null)
            {
                ConnectorClient connector = new ConnectorClient(new System.Uri(message.ServiceUrl));
                foreach (var member in iConversationUpdated.MembersAdded ?? System.Array.Empty<ChannelAccount>())
                {
                    // if the bot is added, then   
                    if (member.Id == iConversationUpdated.Recipient.Id)

You need to check logs from azure, as it already works in local. — Sagar Solanki

It seems that you’d like to catch the ConversationUpdate activity and create&send a fake message to initialize the dialog in order to prompt for one of a set of choices via PromptDialog.Choice() method. I suggest that you can specify Text property of activity before you send it to initialize the dialog, and then you can do different operations by checking the message activity Text property in the dialog.

Based on your scenario, I create the following sample code, which work for me on Web Chat, you can refer to it.

In MessagesController:

else if (activity.Type == ActivityTypes.ConversationUpdate)
{
    // Handle conversation state changes, like members being added and removed
    // Use Activity.MembersAdded and Activity.MembersRemoved and Activity.Action for info
    // Not available in all channels

    IConversationUpdateActivity iConversationUpdated = activity as IConversationUpdateActivity;
    if (iConversationUpdated != null)
    {
        ConnectorClient connector = new ConnectorClient(new System.Uri(activity.ServiceUrl));
        foreach (var member in iConversationUpdated.MembersAdded ?? System.Array.Empty<ChannelAccount>())
        {
            // if the bot is added, then   
            if (member.Id == iConversationUpdated.Recipient.Id)
            {
                var reply = ((Activity)iConversationUpdated).CreateReply("Hi, Welcome to Systenics.");
                await connector.Conversations.ReplyToActivityAsync(reply);

                //set value to Text property
                activity.Text = "show choices";
                await Conversation.SendAsync(activity, () => new EchoDialog());
            }
        }
    }

}

In dialog:

public async Task StartAsync(IDialogContext context)
{
    context.Wait(MessageReceivedAsync);
}


public async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
{
    var activity = await result as Activity;

    var mes = activity.Text?.ToString();

    if (mes == "show choices")
    {
        var descriptions = new string[] { "Request a Quote", "More Information About Jobs" };
        PromptDialog.Choice(
            context: context,
            resume: ChoiceReceivedAsync,
            options: descriptions,
            prompt: "Please select an option below:",
            retry: "Selected option not available.",
            promptStyle: PromptStyle.Auto
            );
    }
    else
    {
        if (mes == "More Information About Jobs")
        {
            var replymes = context.MakeMessage();
            replymes.Text = "Click on this link to know more about jobs [https//www.abc.com](https//www.abc.com)";

            await context.PostAsync(replymes);
        }
        else if (mes == "Request a Quote")
        {
            //your code logic here
        }
        else
        {
            await context.PostAsync($"You sent {activity.Text}");
        }


        context.Wait(MessageReceivedAsync);
    }
}

Test result:

Microsoft bot service work perfectly fine in local but not in webchat channel
