Serialization event handlers that don't have the correct signature will simply not be called, thus bypassing any attempts to augment the automated de/serialization.
|
|
|
|
This rule raises issue when a method marked with one of the following attributes is ``Public``, ``Shared``, is a ``Function`` not a ``Sub``, has type parameters, or does not have a single parameter of type ``System.Runtime.Serialization.StreamingContext``:
|
|
|
|
* ``System.Runtime.Serialization.OnSerializingAttribute``
|
|
* ``System.Runtime.Serialization.OnSerializedAttribute``
|
|
* ``System.Runtime.Serialization.OnDeserializingAttribute``
|
|
* ``System.Runtime.Serialization.OnDeserializedAttribute``
|
