You can use
DateCreated = c.DateTime(nullable: false, defaultValueSql: "GETDATE()")
Usage:
public partial class MyMigration : DbMigration
{
public override void Up()
{
CreateTable("dbo.Users",
c => new
{
Created = c.DateTime(nullable: false, defaultValueSql: "GETDATE()"),
})
.PrimaryKey(t => t.ID);
...
Update 2012-10-10:
As requested by Thiago in his comment, I add a little extra context.
The code above is a migration-file generated by EF Migrations by running Add-Migration MyMigration
as a command in the package manager console. The generated code is based on the models in the DbContext associated with migrations. The answer suggests that you modify the generated script so that a default value is added when the database is created.
