Narrative:
While on an IFR flight plan I had a near miss with another aircraft while in the minneapolis class B airspace just northeast of ZZZ. I was at 4000 ft. Heading direct to ZZZ1 and I saw a VFR target on my ads-B on my multifunctional display inside my airplane the was roughly at my 9 o'clock at 4-5 miles at 3500 ft. On a converging path with me. I made visual contact with the aircraft which was followed shortly after with a traffic alert from ATC and I stated 'traffic in sight'. I continued on my course and watched the aforementioned traffic and noticed that the airplane was getting closer and closer. I noticed on ads-B that the aircraft was climbing and I received a traffic alert from my ads-B system and I saw that the other aircraft was on a collision course with me. I took evasive action and climbed immediately to around 4300 - 4400 ft. Just as the aircraft; which I identified as a [piper twin]; passed around 100 ft. Or less below me. I believe the pilot saw me at the last second because it appeared that they stopped their climb momentarily right before they passed underneath me. I advised ATC that I was climbing for collision avoidance and the controller seemed to have not noticed until I told them which was concerning considering the close proximity of my aircraft to the other aircraft. I think that controllers need to treat all aircraft with the same attention whether or not they are small general aviation aircraft or airliners. Also I think have ads-B displays in aircraft can greatly improve situational awareness in busy/congested airspace.

Narrative: While on an IFR flight plan I had a near miss with another aircraft while in the Minneapolis Class B airspace just northeast of ZZZ. I was at 4000 ft. heading direct to ZZZ1 and I saw a VFR target on my ADS-B on my Multifunctional Display inside my airplane the was roughly at my 9 o'clock at 4-5 miles at 3500 ft. on a converging path with me. I made visual contact with the aircraft which was followed shortly after with a traffic alert from ATC and I stated 'traffic in sight'.
