Here is an example on how to clone an object in a portable class library

I am using Json.net to help. Add the Json.Net nuget package to any project in the solution that uses the PCL

Nuget

Then you an serialize the object into Json and then deserialize it right away to create a clone of a object

    public T CloneObject<T>(T toBeCloned)

    {

        T clone = default(T);

        string serialized = JsonConvert.SerializeObject(toBeCloned);

        clone = JsonConvert.DeserializeObject<T>(serialized);

        return clone;

    }
