当我 运行 我的电报作为后台服务 (IHostedService) 接收时，电报机器人 Console.Readline 阻止整个主机

Question

我的项目有 API 个端点和后台 TelegramBot 通信后台服务，您可以在下面看到我的后台服务：

public class BackgroundWorker: BackgroundService
{
    private readonly IOptions<TelegramSettings> _telegramSettings;
    private readonly IOptions<SqliteConnectionString> _sqlite;
    public BackgroundWorker(IOptions<TelegramSettings> 
telegramSettings, IOptions<SqliteConnectionString> sqlite)
    {
        _telegramSettings = telegramSettings;
        _sqlite = sqlite;
    }
    public override async Task StartAsync(CancellationToken 
cancellationToken)
    {
        await base.StartAsync(cancellationToken);
    }
    protected override Task ExecuteAsync(CancellationToken 
stoppingToken)
    {
        var telegramSocial = new 
TelegramSocial(_telegramSettings,_sqlite);
        telegramSocial.ReceiveMessage();
        return Task.CompletedTask;
    }
}

还有我的 Telegram Bot 接收 如下所示：

public void ReceiveMessage()
 {
     using var cts = new CancellationTokenSource();
     // StartReceiving does not block the caller 
     //thread.Receiving is done on the ThreadPool.
     var receiverOptions = new ReceiverOptions
     {
        AllowedUpdates = {  } // receive all update types
     };
        
  _botClient.StartReceiving(HandleUpdateAsync, 
    HandleErrorAsync, receiverOptions,
    cancellationToken: cts.Token);
    Console.ReadLine();
    // Send cancellation request to stop bot
    cts.Cancel();
}
enter code here

如您所见，Console.ReadLine() 阻止了我的整个主机和我的 APIEndPoints 不起作用

现在我可以做些什么来解决这个问题或用 Console.ReadLine().

替换的东西

Telegram.Bot 17.0.0

Telegram.Bot.Extensions.Polling 1.0.0-alpha.1

.Net Core 5

抱歉英语不好。

更改 StartReceive 方法并仅使用 ReceiveAsync 及其工作并且不要阻止我的主机代码 Att 下面：

public async Task ReceiveMessage()
    {
        using var cts = new CancellationTokenSource();
        // StartReceiving does not block the caller thread. Receiving is 
        //done on the ThreadPool.
        var receiverOptions = new ReceiverOptions
        {
            AllowedUpdates = {  } // receive all update types
        };
        
        await _botClient.ReceiveAsync(HandleUpdateAsync, HandleErrorAsync, 
receiverOptions,
            cancellationToken: cts.Token);
        Console.ReadLine();
        // Send cancellation request to stop bot
        cts.Cancel();
    }
