ReplyToActivity

This method allows you to reply to an activity.

This is slightly different from SendToConversation().

  • SendToConverstion(conversationId) - will append the activity to the end of the conversation according to the timestamp or semantics of the channel.
  • ReplyToActivity(conversationId,ActivityId) - adds the activity as a reply to another activity, if the channel supports it. If the channel does not support nested replies, ReplyToActivity falls back to SendToConversation.

Use ReplyToActivity when replying to a specific activity in the conversation.

Use SendToConversation in all other cases.
