在 IIS 上启动 .NET Core Web API 时出错：“应用程序正在 IIS 进程内运行，但未配置为使用 IIS 服务器”

Question

我已经将.NET Core2.2 API 发布到IISv.10，由于某种原因它响应 500！

我试过

• stdoutLogEnabled="true" （未生成日志文件）
• app.UseDeveloperExceptionPage（无）
• dotnet.exe x.dll 其中 x 是项目名称（表示：未配置侦听端点。绑定到http://localhost:5000）然后它可以在 5000 而不是 IIS 上的指定端口上完美运行

我将不胜感激你的建议。谢谢

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

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>();

launchSettings.json文件：

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:5694",
      "sslPort": 0
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "x": {
      "commandName": "Project",
      "applicationUrl": "http://localhost:5694",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

启动：

public Startup(IConfiguration configuration, ILoggerFactory loggerFactory)
{
    NLog.LogManager.LoadConfiguration(String.Concat(Directory.GetCurrentDirectory(), "/nlog.config"));
    Configuration = configuration;
}

public IConfiguration Configuration { get; }

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.UseCors("CorsPolicy");
    app.UseMvc();
}

我已经重新安装了该.NET Core捆绑包，我从以下位置得到了这个stdout：

如果您在将应用程序托管为 Azure 应用服务时遇到这种情况

添加这个：

<AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel>

在下面

<TargetFramework>netcoreapp3.1</TargetFramework>

在你的主机*.csproj文件中。
