bf luis:generate:cs generates wrong class for "money/currency" prebuilt entity. #1069

What project is affected?

Virtual Assistant and Skill Template

What language is this in?

C#

What happens?

bf luis:generate:cs when called by update_cognitive_models.ps1 does not manage correctly the "money/currency" prebuilt entity.

I have an Hotel entity with two subentities HotelTimeFrame and TotalAmount. TotalAmount being modeled as a prebuilt money entity:

@ ml Hotel
    - @ ml HotelTimeFrame usesFeature MLTimeFrame
    - @ money TotalAmount

With this definition bf luis:generate:cs is generating the MySkillLuis.cs as following, with TotalAmount as string[]:

public class HotelClass
{
	public string[] HotelTimeFrame;
	public string[] TotalAmount;
	[JsonProperty("$instance")]
	public _InstanceHotel _instance;
}
public HotelClass[] Hotel;

This way, I get an exception in the Convert method of the generated class:

public void Convert(dynamic result)
{
	var app = JsonConvert.DeserializeObject<MySkillLuis>(
	JsonConvert.SerializeObject(
		result,
		new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore, Error = OnError }
	)
[...]

I manually changed the class definition as follows, with TotalAmount as Money[], and it worked:

public class HotelClass
{
	public string[] HotelTimeFrame;
	public Money[] TotalAmount;
	[JsonProperty("$instance")]
	public _InstanceHotel _instance;
}
public HotelClass[] Hotel;

But that's quite never a viable solution, since in many environment the update_cognitive_models.ps1 is executed by the ci/cd pipeline.
