Here is a code snippet from Startup.cs:

            if (configuration.GetValue("AZURE_SEARCH_API_ENDPOINT", "") != "")
            {
                services.AddSingleton(new AzureSearchChatDataSource()
                {
                    Endpoint = new Uri(configuration.GetValue<string>("AZURE_SEARCH_API_ENDPOINT")),
                    IndexName = configuration.GetValue<string>("AZURE_SEARCH_INDEX"),
                    Authentication = DataSourceAuthentication.FromApiKey(configuration.GetValue<string>("AZURE_SEARCH_API_KEY")),
                });
            }

I am injecting that into SemanctiKernelBot.cs:

        private readonly string _instructions;
        private readonly string _welcomeMessage;
        private readonly string _endpoint;
        private readonly string _deployment;
        private readonly AzureSearchChatDataSource _chatDataSource;
        private readonly string _apiKey;
        private readonly CanvasApiClient _canvasDataService;

        public SemanticKernelBot(IConfiguration config, ConversationState conversationState, UserState userState, AzureOpenAIClient aoaiClient, AzureSearchChatDataSource chatDataSource, CanvasApiClient canvasDataService, T dialog)
            : base(config, conversationState, userState, dialog)
        {
            _instructions = config["LLM_INSTRUCTIONS"];
            _welcomeMessage = config.GetValue("LLM_WELCOME_MESSAGE", "Hello and welcome to the Semantic Kernel Bot Dotnet!");
            _endpoint = config["AZURE_OPENAI_API_ENDPOINT"];
            _deployment = config["AZURE_OPENAI_DEPLOYMENT_NAME"];
            _apiKey = config["AZURE_OPENAI_API_KEY"];
            _chatDataSource = chatDataSource;
            _canvasDataService = canvasDataService;
        }

I am configuring the chat completion options like so:

            // Define prompt execution settings
            var promptExecutionSettings = new AzureOpenAIPromptExecutionSettings()
            {
                AzureChatDataSource = _chatDataSource,
                ToolCallBehavior = ToolCallBehavior.AutoInvokeKernelFunctions
            };

I've also noticed that plugins (i.e. the wikipedia plugin) are no longer responding.
