Message d'erreur du compilateur: Échec du compilateur : code d'erreur -2146232576.

Bonjour,

En local mon application web tourne très bien, elle fût déployé avec succès il y a quelques temps déjà, mais après modification (rien de systémique) et ré-déploiement, je me retrouve confronté à une erreur de compilation.
Le dossier temporaire .Net a été nettoyé.
Je suis désemparé, je ne comprend pas ce code erreur et impossible de trouver des infos sur le web.

Merci d'avance pour vos réponses.

La page net m'affiche ceci :

Message d'erreur du compilateur: Échec du compilateur : code d'erreur -2146232576.
