Automapper unsupported mapping int16 to enum

Question

AutoMapper 4.1.1

Source Object:

public class Platform_ContentTemplatesModel : OzEfEntity, IEntity<int>
{
    public string TemplateContent { get; set; } 
    public int TemplateIdentifier { get; set; } 
    public short WebsitePropertyId { get; set; }
    public int Id { get; set; } 
}

Destination object:

public class OzCpPlatformContentTemplateItemRecord
{
    public int Id { get; set; }
    public string TemplateContent { get; set; }
    public ContentTemplateIdentifierEnum TemplateIdentifier { get; set; }
    public WebsitePropertyEnum WebsiteProperty { get; set; }
}

Mapping configuraton:

Mapper.CreateMap<Platform_ContentTemplatesModel, OzCpPlatformContentTemplateItemRecord>()
                .ForMember(dest => dest.WebsiteProperty, opt => opt.MapFrom(src => src.WebsitePropertyId));

Now the mapping of TemplateIdentifier from an int to the enum works perfectly. However the mapping of WebsitePropertyid to WebsiteProperty, namely a short to an enum fails with the following exception:

{"Missing type map configuration or unsupported mapping. Mapping types: Int16 -> WebsitePropertyEnum System.Int16 -> WebsitePropertyEnum Destination path: OzCpPlatformContentTemplateItemRecord.WebsiteProperty.WebsiteProperty Source value:1"}

Now I have an enum member with the value of 1. So is the issue here that the underlying type is a short. I cannot change this to an int so how do I work around this?

Make sure that your destination enum maps to a short

public enum WebsitePropertyEnum : short
{
    thing1 = 0,
    thing2 = 1
}
