方法

FindClosestBaseType(IConventionEntityType)

在模型中尋找與指定實體類型相關聯 CLR 類型的實體類型，該類型衍生自指定的實體類型，而且是 CLR 階層中最接近的實體類型。

(繼承來源 InheritanceDiscoveryConventionBase)
ProcessEntityTypeAdded(IConventionEntityTypeBuilder, IConventionContext<IConventionEntityTypeBuilder>)

在實體類型新增至模型之後呼叫。
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。
