我们有一个 .NET Core 控制台应用程序。

static void Main(string[] args)
{
    var environmentName = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");
    var builder = new ConfigurationBuilder()
        .AddJsonFile($"appsettings.json", true, true)
        .AddJsonFile($"appsettings.{environmentName}.json", true, true)
        .AddEnvironmentVariables();
    var configuration = builder.Build();
}

environmentName始终为空。如何ASPNETCORE_ENVIRONMENT在App.config文件中设置？
