How to initialize Automapper when source type is unknown

I have following code:

public static TDest Map2<TDest>(this object sourceObjInstance) where TDest : new()
{
    var itemType = typeof(TDest);
    var item = Activator.CreateInstance(itemType);
    Mapper.Initialize((cfg => cfg.CreateMap<??????, TDest>());
    var result = Mapper.Map(sourceObjInstance, item, sourceObjInstance.GetType(), item.GetType());
    return (TDest)result;
}

So, I don't know where to get generic parameter (????? placeholder) for source object for mapper.initialize method. The sourceObjInstance will be autogenerated class by WCF.

Automapper supports dynamic mapping. Set CreateMissingTypeMaps configuration property when you don't know the source/destination type at compile time:

Mapper.Initialize(cfg => cfg.CreateMissingTypeMaps = true);

object src = new Src();
object dest = new Dest();

Mapper.Map(src, dest);
