Answer 1

With EF 7:

[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
Column(TypeName = "datetime2")]
DateTime? Dateadded { get; set; }

migration script:

AlterColumn("myschema.mytable", "Dateadded", c => c.DateTime(nullable: false, precision: 7, storeType: "datetime2", defaultValueSql: "getutcdate()"));

result:

ALTER TABLE [MySchema].[MyTable] ADD  CONSTRAINT [DF_MySchema.MyTable_Dateadded]  DEFAULT (getutcdate()) FOR [Dateadded]
