Load Assembly in New AppDomain without loading it in Parent AppDomain

Question

I am attempting to load a dll into a console app and then unload it and delete the file completely. The problem I am having is that the act of loading the dll in its own App

Answer 1

This should be easy enough:

namespace Parent {
  public class Constants
  {
    // adjust
    public const string LIB_PATH = @"C:\Collector.dll";
  }

  public interface ILoader
  {
    string Execute();
  }

  public class Loader : MarshalByRefObject, ILoader
  {
    public string Execute()
    {
        var assembly = Assembly.LoadFile(Constants.LIB_PATH);
        return assembly.FullName;
    }
  }

  class Program
  {
    static void Main(string[] args)
    {
      var domain = AppDomain.CreateDomain("child");
      var loader = (ILoader)domain.CreateInstanceAndUnwrap(typeof(Loader).Assembly.FullName, typeof(Loader).FullName);
      Console.Out.WriteLine(loader.Execute());
      AppDomain.Unload(domain);
      File.Delete(Constants.LIB_PATH);
    }
  }
}
