serialization - Need to Seriazlize List<object>, but FXCop complains "Do not expose generic lists" -

i have object need serialize. object contains several properties, including list. fxcop complaining should not expose generic lists, , that, however, due fact can't specify interface based property on object want serialized i'm not sure turn next.

any thoughts?

btw, i'm using xmlserialization, that's not requirement.

i took fxcop's suggestion , wrapped list in collection. blew of code out of water, after few adjustments , running again.

here's code showing before , after:

before:

   public class persistentdataview     {         public string title { get; set; }         private list<object> inputs { get; set;}     } 

after:

    public class persistentdataview     {         private list<object> _inputs;          public string title { get; set; }         public collection<object> inputs         {                         {                 if (_inputs == null)                     _inputs = new list<object>();                  //wrap private field collection.                 return new collection<object>(_inputs);             }         }   }
