// var forSentTableBody = new MailSent { };
context.mailsents.Add(forSentTable);

//context.MailSents.Add(forSentTableBody);
context.SaveChanges();

如果您使用数据库优先模型。您必须将Identity设置为model的StoreGeneratedPattern属性的值。  如果你使用代码第一模型。试试这个

[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
 public Guid ID { get; set; }
