Aircraft; Procedure
Between 'DARTS' intersection and the VNY VOR; while cruising at 8;000 feet I was issued traffic; 6 miles level at 7;500 feet located at my 11 o'clock position. I also overheard the controller; conversing along the same line with the aircraft in question; a Cessna Skylane; proceeding northbound. Neither one of us had the other in sight at the time. A few minutes later the pilot of the Skylane advised the controller that he had me in sight. The controller acknowledged the transmission; and then asked me if I had the traffic in sight. I replied 'negative'. The controller then advised me that the traffic was at my 11 o'clock and 1 mile.At that point I spotted the aircraft which was blending very well with the buildings in the background as it seems to be making a turn to the east. I then stated that I had the traffic in sight. The controller told the Skylane to continue climbing and to maintain VFR. He also advised me that the traffic would continue to climb VFR; which it did coming within 300 feet according to 'Traffic Advisory System' on board. That is when I said to the controller 'That was not good!' I was not given an answer.Though the 'Traffic Advisory System' had detected the aircraft at a certain point; but shortly after the traffic vanished from the screens until I made visual contact with it. The controller issued clearance for the aircraft to continue climbing VFR while too close to my path of flight. I made a comment to ATC that it was not a good situation. ATC should have kept the aircraft at the same altitude until I cross its path; or given me a heading change to the south and an increase in altitude.
Air taxi pilot reported that a VFR aircraft which had them in sight flew too close to them.
