方法

ProcessEntityTypeAdded(IConventionEntityTypeBuilder, IConventionContext<IConventionEntityTypeBuilder>)	在实体类型添加到模型后调用。
ProcessEntityTypeBaseTypeChanged(IConventionEntityTypeBuilder, IConventionEntityType, IConventionEntityType, IConventionContext<IConventionEntityType>)	在实体类型的基类型更改后调用。
ProcessEntityTypeMemberIgnored(IConventionEntityTypeBuilder, String, IConventionContext<String>)	在忽略实体类型成员之后调用。
ProcessForeignKeyNullNavigationSet(IConventionForeignKeyBuilder, Boolean, IConventionContext<IConventionNavigation>)	在外键上的导航设置为 null 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。
ProcessNavigationAdded(IConventionNavigationBuilder, IConventionContext<IConventionNavigationBuilder>)	在将导航添加到实体类型后调用。
ProcessNavigationRemoved(IConventionEntityTypeBuilder, IConventionEntityTypeBuilder, String, MemberInfo, IConventionContext<String>)	从实体类型中删除导航后调用。
ProcessTypeIgnored(IConventionModelBuilder, String, Type, IConventionContext<String>)	在忽略实体类型后调用。
ShouldBeOwned(Type, IConventionModel)	返回一个值，该值指示如果给定的实体类型当前不在模型中，则是否应将其添加为拥有实体类型。
TryGetTargetEntityTypeBuilder(IConventionEntityTypeBuilder, Type, MemberInfo, Nullable<Boolean>, Boolean)	查找或尝试为给定导航成员创建实体类型目标。
