.NET: [Bug]: The MessageInjectingChatClient does not store the historical conversations of injected messages.

[naruto1227]

Description

The MessageInjectingChatClient failed to add the injected messages to the conversation history.

Code Sample

public class MessageInjectingTest
{
    public static async Task Exec()
    {
        var chatClient = OpenApiClientFactory.CreateClient();
       var agent= chatClient.AsAIAgent(new ChatClientAgentOptions()
        {
            EnableMessageInjection = true,
            ChatOptions = new ChatOptions()
            {
                Instructions = "You are a weather forecast specialist, skilled in analyzing weather conditions.",
                Tools = [AIFunctionFactory.Create(GetWeather)]
            }
        });
        var session=await agent.CreateSessionAsync(); 
        await foreach (var item in agent.RunStreamingAsync("获取北京的天气",session))
        {
            Console.Write(item.Text);
        }
    }

    [Description("获取天气预报的信息，输入城市，返回天气的详情")]
    private static string GetWeather([Description("城市的名称：例如上海、北京、杭州")]string city)
    {
        var currentRunContext = AIAgent.CurrentRunContext!;
        if (city=="北京")
        {
            var messageInjectingChatClient = currentRunContext.Agent.GetService<MessageInjectingChatClient>();
            messageInjectingChatClient!.EnqueueMessages(currentRunContext.Session!, [
               new ChatMessage(role:ChatRole.User, content: "我说错了，我想要查询上海的天气")
            ]);
        }

        return $"当前城市：{city}\n 天气：{Random.Shared.Next(20,30)}度 \n 气温：晴天";
    }
}

@naruto1227 You can try to enable the "RequirePerServiceCallChatHistoryPersistence" attribute in the "ChatClientAgentOptions" at the same time.

Like this :

var chatAgent = chatClient.AsAIAgent(new ChatClientAgentOptions()
    {
        EnableMessageInjection = true,
        RequirePerServiceCallChatHistoryPersistence = true,
        ChatOptions = new ChatOptions
        {
            Instructions = "You are a weather forecast specialist, skilled in analyzing weather conditions.",
            Tools = [AIFunctionFactory.Create(GetWeather)]
        }
    });
