I want to broadcast message accross conversations where the bot is present, issuing a command like that :

/broadcast gameid=15 message

For each conversation where is the bot, I save activity.Conversation.Id in state of the conversation and when the bot receive the command /broadcast, it extract all the state of the conversation, filter with the required criteria and sendActivityAsync to all chat using Conversation.Id retrieved in states.

 var activity = new Activity()

 {

     Conversation = new ConversationAccount(id: state.ConversationId),

     Text = "toto",

     Type = ActivityTypes.Message,

     ServiceUrl = turnContext.Activity.ServiceUrl,

     ChannelId = turnContext.Activity.ChannelId

 };

 await turnContext.SendActivityAsync(activity);

But the message is issued only in the chat where the command had been issued, ignoring the Conversation.Id I've setup in the activity.

I do my tests with the bot emulator.

So, is it possible to send activity from a chat to another and if so, what's wrong with my code?
