AutoMapper 8.1 adds a major new feature - attribute-based maps. Attribute maps let you easily declare maps on destination types when you have straightforward scenarios. Instead of: 

public class OrderProfile {  
    public OrderProfile() {
        CreateMap<Order, OrderIndexModel>();
        CreateMap<Order, OrderEditModel>();
        CreateMap<Order, OrderCreateModel>();
    }
}

You can declare your type maps directly on the destination types themselves with AutoMapAttribute: 

[AutoMap(typeof(Order))]
public class OrderIndexModel {  
    // members
}

[AutoMap(typeof(Order))]
public class OrderEditModel {  
    // members
}

[AutoMap(typeof(Order))]
public class OrderCreateModel {  
    // members
}
