Entity Framework - Include Multiple Levels of Prop

Question

The Include() method works quite well for Lists on objects. But what if I need to go two levels deep? For example, the method below will return ApplicationServers with the included properties shown here. However, ApplicationsWithOverrideGroup is another container that holds other complex objects. Can I do an Include() on that property as well? Or how can I get that property to fully load?

As it stands now, this method:

public IEnumerable<ApplicationServer> GetAll()
{
    return this.Database.ApplicationServers
        .Include(x => x.ApplicationsWithOverrideGroup)                
        .Include(x => x.ApplicationWithGroupToForceInstallList)
        .Include(x => x.CustomVariableGroups)                
        .ToList();
}

Will populate only the Enabled property (below) and not the Application or CustomVariableGroup properties (below). How do I make this happen?

public class ApplicationWithOverrideVariableGroup : EntityBase
{
    public bool Enabled { get; set; }
    public Application Application { get; set; }
    public CustomVariableGroup CustomVariableGroup { get; set; }
}

Let me state it clearly that you can use the string overload to include nested levels regardless of the multiplicities of the corresponding relationships, if you don't mind using string literals:

query.Include("Collection.Property")
