c# - Why do I get warning CA2229 (Implement serialization constructors) when inheriting from standard type -


i have class definition this:

[serializable] public class mydictionary: dictionary<string, object> { }

however, code analysis warning:

ca2229 implement serialization constructors add constructor tcpfieldvaluedictionary following signature: 'protected tcpfieldvaluedictionary(serializationinfo info, streamingcontext context)'.

however, generic dictionary has constructor, public modifier.

it easy add constructor (see below), why should done? advantage? 

    protected mydictionary(serializationinfo info, streamingcontext context)         : base(info, context)     { }

constructors aren't inherited. doesn't matter constructors base type has - if want constructor particular signature class, have implement one.

otherwise, default parameterless constructor.
