Portable class library: recommended replacement for [Serializable]

Question

I am porting a .NET Framework C# class library to a Portable Class Library. One recurring problem is how to deal with classes decorated with the [Serializable]

Answer 1

One thing you could do to eliminate the clutter that the constant preprocessor directives causes is to push that off to one new SerializableAttribute class and basically trick the compiler.

#if PORTABLE
namespace System
{
   public class SerializableAttribute : Attribute
   {
       //this does nothing
   }  
}
#endif

Then just continue to decorate your classes with Serializable as normal...
