c# - .NET 5 WorkerService HostingEnvironment.IsDevelopment() 在环境变量 ASPNETCORE

问题描述

正如标题所说，我创建了一个新的 .NET 5 WorkerService 但是当我调用HostingEnvironment.IsDevelopment()它时，即使环境变量ASPNETCORE_ENVIRONMENT设置为Development.

Program.cs 看起来像这样：

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

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
             .ConfigureAppConfiguration((hostContext, builder) =>
             {
                 if (hostContext.HostingEnvironment.IsDevelopment())
                 {
                     builder.AddUserSecrets<Program>();
                 }
             })
            .ConfigureServices((hostContext, services) =>
            {
                var configuration = hostContext.Configuration;

                var settings = new MyAppSettings();
                configuration.GetSection("MyApp").Bind(settings);
                services.AddSingleton(settings);

                services.AddHttpClient();
                services.AddHttpClient<MyAppHttpClient>();
                services.AddHostedService<Worker>();
            })
            .ConfigureLogging(logging =>
            {
                logging.AddEventLog(eventLogSettings =>
                {
                    eventLogSettings.SourceName = "MyAppBooker";
                });
            });
}

环境变量在调试属性下设置，如下所示：
