[Guillermo-Santos]

This is the first of three problems found building Cosmos with different nugget packages.

This one throws a Null Reference exception when scanning the opcodes. Exception Post the exception returned by Visual Studio

How To Reproduce Add the ThunderboltIoc nugget package.

<PackageReference Include="ThunderboltIoc" Version="1.2.3" />

Write a simple service implementation and the register.

    public partial class FooThunderboltRegistration : ThunderboltRegistration
    {
        protected override void Register(IThunderboltRegistrar reg)
        {
            reg.AddScoped<IBarService, BarService>();
        }
    }

    public interface IBarService
    {

    }

    public class BarService : IBarService
    {

    }

Attach the register to the ThunderboltActivator class

ThunderboltActivator.Attach<FooThunderboltRegistration>();

Build the project. Screenshots
