Question How to add a managed compnent to an Entity during authoring?

I have the following managed component

Code (CSharp):

1. public class MainConfig : IComponentData
2. {
3.    public List<string> RessourceNames;
4.    public List<Building> Buildings;
5. }

When I try to use `AddComponent` I get

Code (CSharp):

1. The type 'MainConfig' must be valid unmanaged type (simple numeric, 'bool', 'char', 'void', enumeration type or struct type with all fields of unmanaged types at any level of nesting) in order to use it as a type argument for 'T' parameter

How should I be adding this managed component during the authoring phase?

 

The answer is

Code (CSharp):

1. AddComponentObject(e, config)
