Using Enums in Azure Search Documents

It was my understanding that if you have an enum in a search document, it would be converted to an int. Unless I am doing something wrong, this does not seem to be happening and the only way I can get this to work is by converting the enum to a string. This seems wrong. Can someone tell me if I have done something wrong or if this is just not possible?

Example:

public enum WebSearchRecordType{
    Unknown = 0,
    Doc1 = 1,
    Doc2 = 2
}

public class WebSearchDocument{
    public Guid Id {get;set;}
    public WebSearchRecordType RecordType { get; set; }
}

If I use something like the above while trying to create the index, I get the following error:

Message: "Property recordType has unsupported type Web.Search.WebSearchRecordType\r\nParameter name: propertyType"
