DI doesn't work on "Development" environment

[takutoy]

environment

.NET Core 3.0.100
MicroBatchFramework 1.5.0

repro code

class Program
{
    static async Task Main(string[] args)
    {
        await BatchHost.CreateDefaultBuilder()
            .UseEnvironment("Development") // works fine if this line is commented out
            .ConfigureServices((hostContext, services) =>
            {
                services.AddScoped<IHoge, Hoge>();
            })
            .RunBatchEngineAsync<MyFirstBatch>(args);
    }
}

public interface IHoge
{
    void Test();
}

public class Hoge : IHoge
{
    public void Test() => Console.WriteLine("Hoge");
}

public class MyFirstBatch : BatchBase
{
    private readonly IHoge hoge;

    public MyFirstBatch(IHoge hoge)
    {
        this.hoge = hoge;
    }

    public void Hello()
    {
        hoge.Test();
        Console.WriteLine("MyFirstBatch");
    }
}

expected

Hoge
MyFirstBatch

actual

I found a workaround: use AddSingleton() or AddTransient() instead of AddScoped().
(I just copied AddScoped() from ASP.NET Core sample!)

Same problem occurred on EF Core AddDbContext(), but it can be avoidable by setting ServiceLifetime.

from:

services.AddScoped<IHoge, Hoge>();
services.AddDbContext<BookDbContext>(opt => opt.UseInMemoryDatabase("foo"));

to:

services.AddSingleton<IHoge, Hoge>();
services.AddDbContext<BookDbContext>(opt => opt.UseInMemoryDatabase("foo"), ServiceLifetime.Singleton);

Thank you for reporting!
I've released ver 1.6.0, it includes fix about this issue.

thank you for the quick fix. MicroBatchFramework saves my batch life!
