Je regarde dans la nouvelle API MS et j'obtiens des erreurs tout en suivant les tutoriels. Ceci est mon code complet. J'essaye d'obtenir la couleur des images avec ceci. le retour que je reçois est "Erreur Retour CV" donc je ne reçois pas imageStream nul ni analysisResult. Merci d'avance!Microsoft ProjectOxford Vision API ClientException Erreur
