Breaking ChangeBreaking - If the method is visible outside the assembly.

Non Breaking - If the method is not visible outside the assembly.

A method that handles a serialization event does not have the correct signature, return type, or visibility.

A method is designated a serialization event handler by applying one of the following serialization event attributes:

Serialization event handlers take a single parameter of type System.Runtime.Serialization.StreamingContext, return void, and have private visibility.

To fix a violation of this rule, correct the signature, return type, or visibility of the serialization event handler.

Do not suppress a warning from this rule.

The following example shows correctly declared serialization event handlers.

using System;
using System.Runtime.Serialization;

namespace UsageLibrary
{
   [SerializableAttribute]
   public class SerializationEventHandlers
   {
      [OnSerializingAttribute]
      void OnSerializing(StreamingContext context) {}

      [OnSerializedAttribute]
      void OnSerialized(StreamingContext context) {}

      [OnDeserializingAttribute]
      void OnDeserializing(StreamingContext context) {}

      [OnDeserializedAttribute]
      void OnDeserialized(StreamingContext context) {}
   }
}
