推荐答案

这不是通用的引用计数功能，它只是 CodeLens 的功能之一.CodeLens 仅适用于 Visual Studio 2015 Pro 及更高版本.在 Visual Studio 2013 中，它是 Ultimate 独有的功能.

This isn't a generic reference counting feature, it's just one of the features of CodeLens. CodeLens is only available in Visual Studio 2015 Pro and above. In Visual Studio 2013 it was a Ultimate-only feature.

更新

正如其他人所指出的，安装 SSDT 或 SSMS 2016 也可以启用 CodeLens.这是因为 VS 2015 Community 是 Pro，具有不同的许可证和一些缺少的扩展，例如 CodeLens.只要安装了扩展程序的二进制文件和设置，社区就会激活该扩展程序.

As others have noted, installing SSDT or SSMS 2016 may enable CodeLens as well. That's because VS 2015 Community is Pro, with a different license and some missing extensions like CodeLens. As long as an extension's binaries and settings are installed, Community will activate the extension.

2019 年更新

CodeLens 一直是仅在 Visual Studio Enterprise 中发现的功能，但在即将发布的 Visual Studio 2019 预览版中会发生变化，届时它也将可用于社区版，可能在 2019 年"Visual Studio 2019 的新增功能

"CodeLens has been a feature found only in Visual Studio Enterprise, but that will change in an upcoming preview of Visual Studio 2019, when it will also be available for the Community edition, likely in 2019" What's New in Visual Studio 2019
