.net core 特定于环境的appsettings未加载其数据

当我尝试使用自定义appsettings.{environment}.json文件时，即使ASPNETCORE_环境变量正确设置为“Local”，并且配置源中引用了appsettings.Local.json文件，也不会从中读取任何数据，只会从appsettings.json读取数据

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
    WebHost.CreateDefaultBuilder(args)                
        .ConfigureAppConfiguration((context, config) =>
        {

            // Configure the app here.
            var env = context.HostingEnvironment;
            //var environmentName = 

            config.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true, reloadOnChange: true);
            config.AddEnvironmentVariables();
        })
        .UseStartup<Startup>();

我要做的第一件事是将其更改为

可选：false

，并确保它正在查找文件。这不要紧，但您添加的源实际上是您显示的列表中的

。是的，就是这样。我的生成未将其生成到/bin文件夹中
