方法

AreIndexedBy(IReadOnlyList<IConventionProperty>, Boolean, IReadOnlyList<IConventionProperty>, Boolean)	傳回值，指出現有索引是否已經涵蓋指定的屬性。
CreateIndex(IReadOnlyList<IConventionProperty>, Boolean, IConventionEntityTypeBuilder)	建立 IConventionIndex。
ProcessEntityTypeBaseTypeChanged(IConventionEntityTypeBuilder, IConventionEntityType, IConventionEntityType, IConventionContext<IConventionEntityType>)	在實體類型的基底類型變更之後呼叫。
ProcessForeignKeyAdded(IConventionForeignKeyBuilder, IConventionContext<IConventionForeignKeyBuilder>)	在將外鍵新增至實體類型之後呼叫。
ProcessForeignKeyPropertiesChanged(IConventionForeignKeyBuilder, IReadOnlyList<IConventionProperty>, IConventionKey, IConventionContext<IReadOnlyList<IConventionProperty>>)	在外鍵屬性或主體索引鍵變更之後呼叫。
ProcessForeignKeyRemoved(IConventionEntityTypeBuilder, IConventionForeignKey, IConventionContext<IConventionForeignKey>)	移除外鍵之後呼叫。
ProcessForeignKeyUniquenessChanged(IConventionForeignKeyBuilder, IConventionContext<Nullable<Boolean>>)	在外鍵的唯一性變更之後呼叫。
ProcessIndexAdded(IConventionIndexBuilder, IConventionContext<IConventionIndexBuilder>)	在索引新增至實體類型之後呼叫。
ProcessIndexRemoved(IConventionEntityTypeBuilder, IConventionIndex, IConventionContext<IConventionIndex>)	移除索引之後呼叫。
ProcessIndexUniquenessChanged(IConventionIndexBuilder, IConventionContext<Nullable<Boolean>>)	變更索引的唯一性之後呼叫。
ProcessKeyAdded(IConventionKeyBuilder, IConventionContext<IConventionKeyBuilder>)	在將索引鍵新增至實體類型之後呼叫。
ProcessKeyRemoved(IConventionEntityTypeBuilder, IConventionKey, IConventionContext<IConventionKey>)	從實體類型中移除索引鍵之後呼叫。
ProcessModelFinalizing(IConventionModelBuilder, IConventionContext<IConventionModelBuilder>)	當模型完成時呼叫。
