Second child container not resolving type properly with Hierarchical Lifetime

[laxmanrapolu]

We have been using Unity version older than 5.2.1 and now started upgrading to newer versions (5.7.0).

Our previous code was working fine because of this issue #35 , but with the upgrade it started breaking.

We followed the suggestion mentioned in the above issue of registering concrete class explicitly. It worked fine when we have one child container, but is not working with second child container.

Below is the code

public class Program
{

public interface IUnitOfWork
{
}

public class Dtrcontext : IUnitOfWork
{
		
}


public void Main()
{
	IUnityContainer container = new UnityContainer();
	container.RegisterType<IUnitOfWork, Dtrcontext>(new HierarchicalLifetimeManager());
	container.RegisterType<Dtrcontext>(new HierarchicalLifetimeManager());
	var child1 = container.CreateChildContainer();
	var child2 = container.CreateChildContainer();
	
	var a = container.Resolve<Dtrcontext>();
	var b = child1.Resolve<Dtrcontext>();
	var c = child1.Resolve<IUnitOfWork>();
	var d = child2.Resolve<Dtrcontext>();
	var e = child2.Resolve<IUnitOfWork>();
	
	Console.WriteLine("a=b?" +(a==b ).ToString());
	Console.WriteLine(" b=c? " +(b==c ).ToString());
	Console.WriteLine(" d=e? " +(d==e ).ToString());
	Console.WriteLine(" b=d? " +(b==d ).ToString());
}

}

Result :
a=b?False
b=c? True
d=e? False --> This is expected to be true.
b=d? False

Wanted to know if this is a know issue and is there any solution.

Version 5.2.1 was somewhat 'rushed' and had multiple issues. I would recommend to upgrade to the latest.
