我正在尝试向 BOT V4 中的 MS 团队发送一些主动消息，但它不起作用。 它可以在网络聊天和模拟器中运行，但在 MS Teams 中不起作用。
当我在下面放置代码以连接到 MS 团队时，主动消息现在在 Webchat 和模拟器中也不起作用。 我收到的错误消息是：
InvalidOperationException: Unable to resolve service for type 'Microsoft.Bot.Connector.Authentication.ICredentialProvider' while attempting to activate 'Intelbot.Controllers.NotifyController'.
你能帮帮我吗？ 谢谢

您的构造函数正在请求具体类，SimpleCredentialProvider，当它应该请求接口ICredentialProvider时，
改变：
public NotifyController(... SimpleCredentialProvider CredentialProvider)
自：
public NotifyController(... ICredentialProvider CredentialProvider)
[...]
_credentialProvider = CredentialProvider as ConfigurationCredentialProvider;
这假设您在Startup.cs中有这个：
services.AddSingleton<ICredentialProvider, ConfigurationCredentialProvider>();
相反，如果您有更类似的东西：
services.AddBot<LuisTranslatorBot>(options =>
{
options.CredentialProvider = new SimpleCredentialProvider(endpointService.AppId, endpointService.AppPassword);
。您需要使用：
ICredentialProvider credentialProvider
