I am looking at using EViL http://www.codeplex.com/evil to do some simple validation, is it possible to get the code generator to add the attributes when it writes the classes?

something like:

        /// <summary> The Comment property of the Entity Comment<br/><br/>
        /// </summary>
        /// <remarks>Mapped on  table field: "Comment"."Comment"<br/>
        /// Table field type characteristics (type, precision, scale, length): VarChar, 0, 0, 2147483647<br/>
        /// Table field behavior characteristics (is nullable, is PK, is identity): false, false, false</remarks>
        [ValidateMinLength(1, "Comment must not be empty")]
        public virtual System.String Comment
        {
            get { return (System.String)GetValue((int)CommentFieldIndex.Comment, true); }
            set { SetValue((int)CommentFieldIndex.Comment, value); }
        }

I know you do your own validation, just looking into all the options. And EVil is such a cool name

Yes, you can modify the code generation templates or use your own ones. But according to which criteria the validation attributes/rules will be written? I guess you have to manually write them in the generated code, or am I missing something here?
