不支持构建IHostBuilder的此实现

Question

我正在尝试配置IHostBuilder并得到以下错误。

不支持构建IWebHostBuilder的实现。

我不知道为什么这是抱怨IHostBuilder。我在Program.cs中的IHostBuilder配置:

var host = Host.CreateDefaultBuilder(args).
UseWindowsService().
ConfigureWebHostDefaults(webBuiler =>
{
webBuiler.UseKestrel(k =>
{
k.Listen(IPAddress.Parse(componentsModel.LaunchSetting.LaunchIP), componentsModel.LaunchSetting.LaunchHTTPSPort, listenOptions =>
{
if (certificate != null)
{
listenOptions.UseHttps(certificate);
}
});
k.Listen(IPAddress.Parse(componentsModel.LaunchSetting.LaunchIP), componentsModel.LaunchSetting.LaunchPort);
}).
UseContentRoot(Directory.GetCurrentDirectory()).ConfigureLogging(logging =>
{
logging.SetMinimumLevel(logLevel);
logging.AddDebug();
logging.AddFile(f =>
{
f.LogDirectory = logDirectory;
f.FileName = fileName;
});
}).UseStartup<Startup>()
.UseApplicationInsights()
.Build()
.Run();
});

我加:

System.NotSupportedException
HResult=0x80131515

Answer 1

删除这两行

.Build()
.Run();

应该是main方法的一部分

public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
}
