Here is a sample of what I'm trying to build using a dynamic module

public class Thing
{
public Thing() {}
public Thing childThing { get; set; }
}

PropertyBuilder propertyBuilder = typeBuilder.DefineProperty( propertyName, PropertyAttributes.HasDefault, propertyType, null);

How do I get a reference to type Thing before typeBuilder.CreateType() is called?

The TypeBuilder inherits System.Type class.
So we can use the typeBuilder instance as propertyType.

PropertyBuilder propertyBuilder = typeBuilder.DefineProperty( propertyName, PropertyAttributes.HasDefault, typeBuilder, null);
