EF 6 + Connecteur DevArt Mysql + MONO

Question

C'est ma première expérience à déployer .net sur debian. Mon application a été créée et testée dans win 7 vs2012 en utilisant le connecteur Devart mysql en utilisant la première méthode de base de données, après que j'ai commencé à le déployer sur Linux. J'ai rencontré un tas d'obstacles !! Je suis hors de mes nerfs ... quelqu'un peut-il m'aider? Avant que je pensais acheter connecteur Devart mysql édition prof ... Voici ma pile

Answer 1

Cela ressemble à un bug Mono. Essayez la solution de contournement suivante: modifiez la valeur de propriété de modèle "Metadata Artifact Processing" de "Embed In Output Assembly" à "Copy To Output Directory". Enregistrez le modèle, reconstruisez le projet sous Windows pour vous assurer qu'il fonctionne et déployez-le sur Mono.

Answer 2

L'erreur est claire: cette méthode n'est pas implémentée en mono.

Mono est un projet open source. Sans les contributions de personnes comme vous, il ne peut pas continuer à évoluer. S'il vous plaît envisager de contribuer une implémentation à la méthode (ne regardez pas les sources MS, car ce ne serait pas valide).
