What to do vs. Vi

Playing Vayne and she just ults and does some retarded burst, killing me instantly. The only way I can beat her is with flash. When that isn't up I get demolished. Idk whether its fps drops, but anytime I pick an ADC, no matter which one, I die to Vi. I don't die to Yasuo. I don't die to LB. I don't die to Zed. I die to stupid Vi. Any tips vs. her happy meal self?
