方法

AreIndexedBy(IReadOnlyList<IConventionProperty>, Boolean, IReadOnlyList<IConventionProperty>, Boolean)	返回一个值，该值指示给定属性是否已由现有索引覆盖。
CreateIndex(IReadOnlyList<IConventionProperty>, Boolean, IConventionEntityTypeBuilder)	创建 IConventionIndex。
ProcessEntityTypeBaseTypeChanged(IConventionEntityTypeBuilder, IConventionEntityType, IConventionEntityType, IConventionContext<IConventionEntityType>)	在实体类型的基类型更改后调用。
ProcessForeignKeyAdded(IConventionForeignKeyBuilder, IConventionContext<IConventionForeignKeyBuilder>)	在将外键添加到实体类型后调用。
ProcessForeignKeyPropertiesChanged(IConventionForeignKeyBuilder, IReadOnlyList<IConventionProperty>, IConventionKey, IConventionContext<IReadOnlyList<IConventionProperty>>)	在更改外键属性或主体键后调用。
ProcessForeignKeyRemoved(IConventionEntityTypeBuilder, IConventionForeignKey, IConventionContext<IConventionForeignKey>)	在删除外键后调用。
ProcessForeignKeyUniquenessChanged(IConventionForeignKeyBuilder, IConventionContext<Nullable<Boolean>>)	在更改外键的唯一性后调用。
ProcessIndexAdded(IConventionIndexBuilder, IConventionContext<IConventionIndexBuilder>)	在将索引添加到实体类型后调用。
ProcessIndexRemoved(IConventionEntityTypeBuilder, IConventionIndex, IConventionContext<IConventionIndex>)	在删除索引后调用。
ProcessIndexUniquenessChanged(IConventionIndexBuilder, IConventionContext<Nullable<Boolean>>)	在索引的唯一性更改后调用。
ProcessKeyAdded(IConventionKeyBuilder, IConventionContext<IConventionKeyBuilder>)	在将键添加到实体类型后调用。
ProcessKeyRemoved(IConventionEntityTypeBuilder, IConventionKey, IConventionContext<IConventionKey>)	从实体类型中删除键后调用。
ProcessModelFinalizing(IConventionModelBuilder, IConventionContext<IConventionModelBuilder>)	在最终确定模型时调用。
