'NonSerialized' attribute will not affect this member because its containing class is not exposed as 'Serializable'

By default, classes and their members aren't binary-serializable. The NonSerializedAttribute attribute is only needed if a member of a binary-serializable class should not be binary serialized.

Error ID: BC30772

To correct this error

• Add the SerializableAttribute attribute to the class.

  —or—

• Remove the NonSerializedAttribute attribute from the member.
