public Author Author { get; set; }Gets or sets a value indicating whether this message has been edited.
public bool IsEdited { get; set; }Gets a value indicating whether this message is a reply to more than one message.
public bool IsMultiReply { get; }Gets a value indicating whether this message is a reply to one or more messages.
public bool IsReply { get; }Gets the author of the first this message replies to, or null when this is not a reply.
public Author ReplyToAuthor { get; }ReplyToAuthors
IEnumerable<Author>
Gets the unique authors of all messages this message is replying to.
public IEnumerable<Author> ReplyToAuthors { get; }Gets or sets the message this message is replying to. When set, replaces any existing entries in ReplyToMessages. Returns the first entry when getting.
public ChatMessage ReplyToMessage { get; set; }Gets a preview text of the reply message(truncated if necessary). For multi-reply, returns a combined preview.
public string ReplyToMessagePreview { get; }ReplyToMessages
IList<ChatMessage>

public IList<ChatMessage> ReplyToMessages { get; }Gets the count of messages this message is replying to.
public int ReplyToMessagesCount { get; }Gets or sets the date and time associated with this instance.
public DateTime TimeStamp { get; set; }Gets or sets a user-defined object that contains custom data associated with this instance.

Methods
Raises the PropertyChanged event to notify listeners that a property value has changed.
protected virtual void OnPropertyChanged(string propertyName)The name of the property that changed. This value is passed to event handlers to identify the property that was updated.
Override this method in a derived class to provide custom logic when a property value changes. This method is typically called by property setters to implement the INotifyPropertyChanged pattern.
Events
Occurs when a property value changes.
public event PropertyChangedEventHandler PropertyChangedImplements:
This event is typically raised by classes that implement the INotifyPropertyChanged interface to notify clients, such as data-binding frameworks, that a property value has changed. Handlers attached to this event receive the name of the property that changed in the PropertyChangedEventArgs parameter.
