Syntax
[AttributeUsage(AttributeTargets.Property)]
public sealed class FirestoreDocumentUpdateTimestampAttribute : Attribute
Remarks
This attribute must only be applied to properties of DateTime, DateTimeOffset, Timestamp, or the nullable equivalents, or a protobuf Timestamp. This attribute is ignored when serializing a document to Firestore. This attribute must not be applied on a property which also has FirestorePropertyAttribute. When deserializing a snapshot representing a missing document, nullable properties will be set to a null value; non-nullable properties will be set to the default value of the type (0001-01-01 for DateTime and DateTimeOffset, 1970-01-01 for Timestamp).
