ActivityHandler.OnMembersAddedAsync Method

Definition

Override this in a derived class to provide logic for when members other than the bot join the conversation, such as your bot's welcome logic.

abstract member OnMembersAddedAsync : System.Collections.Generic.IList<Microsoft.Bot.Schema.ChannelAccount> * Microsoft.Bot.Builder.ITurnContext<Microsoft.Bot.Schema.IConversationUpdateActivity> * System.Threading.CancellationToken -> System.Threading.Tasks.Task
override this.OnMembersAddedAsync : System.Collections.Generic.IList<Microsoft.Bot.Schema.ChannelAccount> * Microsoft.Bot.Builder.ITurnContext<Microsoft.Bot.Schema.IConversationUpdateActivity> * System.Threading.CancellationToken -> System.Threading.Tasks.Task

Parameters
