Aircraft X was cleared down to 12;000 ft. I was dealing with a VFR aircraft requesting flight following when I noticed Aircraft X was below 11;000 ft. in a 12;000 ft. Minimum Vectoring Area. I queried him about his altitude and he said he was in VFR conditions and forgot to tell me. He then reported destination airport in sight and was cleared for a Visual Approach. He subsequently canceled IFR. Remind pilots not to descend without a clearance.
Center Controller reported an aircraft left its assigned altitude and descended below the Minimum Vectoring Altitude.
