Is it possible to define DateTime properties in entity objects that are of Kind == DateTimeKind.Utc by using either the .edmx file, or a t4 template?
W
Yes, it would be possible to use a custom T4 template.
You'd just have to adjust your property setters and getters.
It might be easier to attempt a POCO approach;
