方法

CreateJoinEntityType(String, IConventionSkipNavigation)	创建联接实体类型并配置相应的外键。
CreateSkipNavigationForeignKey(IConventionSkipNavigation, IConventionEntityTypeBuilder)	在给定的实体类型上创建一个外键，供给定的跳过导航使用。
GenerateJoinTypeName(IConventionSkipNavigation)	为新的联合实体类型生成唯一名称。
ProcessSkipNavigationAdded(IConventionSkipNavigationBuilder, IConventionContext<IConventionSkipNavigationBuilder>)	在将跳过导航添加到实体类型后调用。
ProcessSkipNavigationForeignKeyChanged(IConventionSkipNavigationBuilder, IConventionForeignKey, IConventionForeignKey, IConventionContext<IConventionForeignKey>)	在跳过导航逆向更改后调用。
ProcessSkipNavigationInverseChanged(IConventionSkipNavigationBuilder, IConventionSkipNavigation, IConventionSkipNavigation, IConventionContext<IConventionSkipNavigation>)	在跳过导航逆向更改后调用。
ProcessSkipNavigationRemoved(IConventionEntityTypeBuilder, IConventionSkipNavigation, IConventionContext<IConventionSkipNavigation>)	从实体类型中删除跳过导航后调用。
ShouldCreateJoinType(IConventionSkipNavigation)	检查是否需要新的联接实体类型。
