ProcessEntityTypeBaseTypeChanged(IConventionEntityTypeBuilder, IConventionEntityType, IConventionEntityType, IConventionContext<IConventionEntityType>)	在實體類型的基礎類型變更後呼叫。
ProcessForeignKeyAdded(IConventionForeignKeyBuilder, IConventionContext<IConventionForeignKeyBuilder>)	在實體類型中加入外鍵後呼叫。
ProcessForeignKeyPropertiesChanged(IConventionForeignKeyBuilder, IReadOnlyList<IConventionProperty>, IConventionKey, IConventionContext<IReadOnlyList<IConventionProperty>>)	在外鍵屬性或主鍵變更後被呼叫。
ProcessForeignKeyRemoved(IConventionEntityTypeBuilder, IConventionForeignKey, IConventionContext<IConventionForeignKey>)	在移除外金鑰後呼叫。
ProcessForeignKeyUniquenessChanged(IConventionForeignKeyBuilder, IConventionContext<Nullable<Boolean>>)	在外鍵唯一性變更後被呼叫。
ProcessIndexAdded(IConventionIndexBuilder, IConventionContext<IConventionIndexBuilder>)	在實體類型新增索引後呼叫。
ProcessIndexRemoved(IConventionEntityTypeBuilder, IConventionIndex, IConventionContext<IConventionIndex>)	在移除索引後呼叫。
ProcessIndexUniquenessChanged(IConventionIndexBuilder, IConventionContext<Nullable<Boolean>>)	在索引的唯一性改變後呼叫。
ProcessKeyAdded(IConventionKeyBuilder, IConventionContext<IConventionKeyBuilder>)	在實體類型中加入鍵數後呼叫。
ProcessKeyRemoved(IConventionEntityTypeBuilder, IConventionKey, IConventionContext<IConventionKey>)	在將某個鍵從實體類型中移除後呼叫。
ProcessModelFinalizing(IConventionModelBuilder, IConventionContext<IConventionModelBuilder>)	當模型正在定案時會被召喚。
