I am trying to create a structure similar to the IHosted Service structure in ASP.Net Core with ASP.Net Framework 4.8, but I could not create the structure I wanted.

project-structure

Startup.cs

public partial class Startup
{
    private IConfiguration Conf { get; }
    public Startup()
    {
        var builder = new Microsoft.Extensions.Configuration.ConfigurationBuilder()
            //.SetBasePath(AppDomain.CurrentDomain.BaseDirectory)
            .AddJsonFile("appsettings.json");
        Conf = builder.Build();
    }
    public void Configuration(IAppBuilder app)
    {
        app.UseHangfireAspNet(GetHangfireServers);
        app.UseHangfireDashboard();
    }
    private IEnumerable<IDisposable> GetHangfireServers()
    {
        Hangfire.GlobalConfiguration.Configuration
            .SetDataCompatibilityLevel(CompatibilityLevel.Version_180)
            .UseSimpleAssemblyNameTypeSerializer()
            .UseRecommendedSerializerSettings()
            .UseSqlServerStorage(Conf.GetSection("ConnectionStrings")["HangFireConnectionString"]);
        
        yield return new BackgroundJobServer();
    }
    protected static string GetXmlCommentsPath()
    {
        return System.String.Format($@"{0}binMyApi.XML",
                System.AppDomain.CurrentDomain.BaseDirectory);
    }
}

Global.asax.cs

 public class WebApiApplication : System.Web.HttpApplication
 {
     protected void Application_Start()
     {
         AreaRegistration.RegisterAllAreas();
         System.Web.Http.GlobalConfiguration.Configure(WebApiConfig.Register);
         FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
         RouteConfig.RegisterRoutes(RouteTable.Routes);
         UnityConfig.RegisterComponents();

     }
     
 }
