Here the constructor of the ReaderService Class, requires 3 arguments:
ReaderService(ILogger<ReaderService> logger, IOptions<ReaderOptions> optionsAccessor, IHostApplicationLifetime applicationLifetime)

But when adding the service "ReaderService" to the host, nothing is passed:
services.AddHostedService<ReaderService>();

This line is missing from last version of "Startup.cs":
services.Configure<ReaderOptions>(Configuration.GetSection("Reader"));

Hi,
