title: How to run .NET Core Console app using generic host builder
body: <p>I am trying to figure out how to use hostbuilder pattern to run a console app (not a windows service). Intent is to keep the flow as similar to a WebApi to keep development practices similar. I have seen samples for using HostedService or BackGroundService, where they want to run it as a windows service. But If I am looking to run a simple console app, where do I specify my entrypoint class and method? From hostbuilder.Build(), I can see Run() and RunAsync() methods. But I am unable to figure out what will it execute?</p>
  <p>I have seen other examples of where you can create servicecollection and then use serviceprovider.GetService().SomeMethod() to start the process. But that kind of deviates from what we want to do. So please suggest how to specify startup process. We are using 3.1 .Net Core.</p>
  <pre><code>class Program
  {
      static async void Main(string[] args)
      {
          var host = CreateHostBuilder(args).Build();
          await host.RunAsync();
      }
  
      public static IHostBuilder CreateHostBuilder(string[] args) =&gt;
      Host.CreateDefaultBuilder(args)
          .ConfigureServices((hostBuilderContext, serviceCollection) =&gt; new Startup(hostBuilderContext.Configuration).ConfigureServices(serviceCollection))
          .UseSerilog()
          ; 
  
  }
  </code></pre>
