Implicit cast converts null to object

In ServiceOverride.cs L82 the implicit cast converts a ServiceOverride of null into an object. This took me a while to figure out because it is behavior I never saw before. Is this intended?

public static implicit operator Dependency(ServiceOverride item)
{
    return new Dependency(item);
}

I would have expected the cast like this:

public static implicit operator Dependency(ServiceOverride item)
{
    return item == null ? null : new Dependency(item);
}

I am gonna do it tonight and open a PR. Alright?

Thanks. I will try if I am now able to work on the code. Would love to contribute.
