Reproduce NPE in Pulumi .NET SDK

MyStack.cs

/*

To reliably hit the race NullPointerException with Pulumi, modify Pulumi.Core Resource.cs constructor to introduce a delay:

            + System.Threading.Thread.Sleep(100);
            + System.Console.WriteLine($"Delaying resource: {name}");

            Deployment.InternalInstance.ReadOrRegisterResource(this, remote, urn => new DependencyResource(urn), args, options);
