.NET Core 是否支持 SqlDependency？

Question

是否可以在 .NET Core v1.1 应用程序中利用 System.Data.SqlClient.SqlDependency？ System.Data.SqlClient 中的大多数其他类和方法似乎都可用，但 SqlDependency 除外。

本质上，我试图在表数据更改时订阅 SQL 通知，然后更新客户端的 UI，因此如果 .NET Core 不提供 SqlDependency，我愿意采用其他方法来实现此目的。

提前致谢！这是我完整的 project.json 文件：

GitHub 上有一个基于 .Net Core 的开源解决方案： https://github.com/dyatchenko/ServiceBrokerListener

但是，我不确定性能，因为似乎多个客户端应用程序正在侦听更改正在创建专用队列。 因此，它的扩展性可能不如原始的 SqlDependency。

根据https://github.com/dotnet/corefx/issues/8188，它会出现在 .NET Core 2.1 中，但我还没有看到任何关于用法是否与 .NET Framework 不同的信息。我希望不会。
