(继承自 InheritanceDiscoveryConventionBase)

方法

FindClosestBaseType(IConventionEntityType)

在模型中查找一个实体类型，该实体类型与给定实体类型的关联 CLR 类型派生自且是 CLR 层次结构中最近的 CLR 类型。

(继承自 InheritanceDiscoveryConventionBase)
ProcessEntityTypeAdded(IConventionEntityTypeBuilder, IConventionContext<IConventionEntityTypeBuilder>)

在实体类型添加到模型后调用。
ProcessForeignKeyOwnershipChanged(IConventionForeignKeyBuilder, IConventionContext<Nullable<Boolean>>)

在更改外键的所有权值后调用。
ProcessForeignKeyRemoved(IConventionEntityTypeBuilder, IConventionForeignKey, IConventionContext<IConventionForeignKey>)

在删除外键后调用。
