方法

ProcessEntityTypeAdded(IConventionEntityTypeBuilder, IConventionContext<IConventionEntityTypeBuilder>)	在實體類型新增至模型之後呼叫。
ProcessEntityTypeBaseTypeChanged(IConventionEntityTypeBuilder, IConventionEntityType, IConventionEntityType, IConventionContext<IConventionEntityType>)	在實體類型的基底類型變更之後呼叫。
ProcessEntityTypeMemberIgnored(IConventionEntityTypeBuilder, String, IConventionContext<String>)	忽略實體類型成員之後呼叫。
ProcessForeignKeyNullNavigationSet(IConventionForeignKeyBuilder, Boolean, IConventionContext<IConventionNavigation>)	在外鍵上將導覽設定為 null 之後呼叫。
ProcessForeignKeyOwnershipChanged(IConventionForeignKeyBuilder, IConventionContext<Nullable<Boolean>>)	在外鍵的擁有權值變更之後呼叫。
ProcessForeignKeyRemoved(IConventionEntityTypeBuilder, IConventionForeignKey, IConventionContext<IConventionForeignKey>)	移除外鍵之後呼叫。
ProcessNavigationAdded(IConventionNavigationBuilder, IConventionContext<IConventionNavigationBuilder>)	在導覽新增至實體類型之後呼叫。
ProcessNavigationRemoved(IConventionEntityTypeBuilder, IConventionEntityTypeBuilder, String, MemberInfo, IConventionContext<String>)	從實體類型中移除導覽之後呼叫。
ProcessTypeIgnored(IConventionModelBuilder, String, Type, IConventionContext<String>)	忽略實體類型之後呼叫。
ShouldBeOwned(Type, IConventionModel)	傳回值，指出如果指定的實體類型目前不在模型中，是否應該新增為擁有。
TryGetTargetEntityTypeBuilder(IConventionEntityTypeBuilder, Type, MemberInfo, Nullable<Boolean>, Boolean)	尋找或嘗試為指定的導覽成員建立實體類型目標。
