Narrative:
We were heading east at 3;000 MSL with poor visibility because of the rising sun and in radar contact with approach control. The TAS in our airplane picked up a target directly in our direction of flight at five miles and at our altitude. Approach did not point out the traffic; so I queried the controller. He acknowledged the traffic; but gave no resolution to the conflict. Our taws gave an aural traffic alert at 2.5 miles. I asked the controller for a descent from 3;000 to 2;000 and immediately started a descent to avoid traffic. The controller granted the altitude change and the approaching aircraft acknowledged that they had us in sight. After the traffic passed I asked for and was granted a climb back to 3;000 MSL. We then proceeded as filed.
