Name

Overrides the persisted field name (defaults to the C# field name). Used as the schema-match key when the database is reopened.

public string Name { get; set; }

PreviousName

Former Name of this field, set when it is renamed so the persisted field can be matched and carried forward. null when never renamed.

public string PreviousName { get; set; }
