c# - Entity Framework Core - Lazy Loading

Question

Bowing to my Visual Studios request, I started my latest project using Entity Framework Core (1.0.1)

So writing my database models as I always have using the 'virtual' specifier to enable lazy loading for a List. Though when loading the parent table it appears that the child list never loads.

Parent Model

public class Events
{
    [Key]

    public int EventID { get; set; }
    public string EventName { get; set; }
    public virtual List<EventInclusions> EventInclusions { get; set; }
}

Child Model

public class EventInclusions
{
    [Key]
    public int EventIncSubID { get; set; }
    public string InclusionName { get; set; }
    public string InclusionDesc { get; set; }
    public Boolean InclusionActive { get; set; }

}

Adding new records to these tables seems to work as I am used to where I can nest the EventInclusions records as a List inside the Events record.

Though when I query this table

_context.Events.Where(e => e.EventName == "Test")

The Issue

EventInclusions will return a null value regardless of the data behind the scenes.

After reading a bit I am getting the feeling this is a change between EF6 which I normally use and EF Core

I could use some help in either making a blanket Lazy Loading on statement or figuring out the new format for specifying Lazy Loading.

Lazy loading is now available on EF Core 2.1 and here is link to the relevant docs:
