public virtual int SaveChanges ();

abstract member SaveChanges : unit -> int
override this.SaveChanges : unit -> int

Public Overridable Function SaveChanges () As Integer

Returns

Int32

Returns

Int32

The number of state entries written to the underlying database. This can include state entries for entities and/or relationships.
