在VS 2017自定义项目系统中,如何在解决方案浏览器中使项目项加粗?

common-project-system extensibility vs-extensibility visual-studio-2017 visual-studio

Tara McGrew · 技术社区 · 7 年前

我正在为VS 2017编写一个项目系统扩展,用我的语言编写的每个项目都有一个文件,即“启动文件”。我希望该文件在解决方案资源管理器中显示为粗体。

Python Tools for VS 做我想要的,但我的扩展是建立在新的项目系统框架(CPS)上的。CPS更改解决方案资源管理器项外观的方法是实现 IProjectTreePropertiesProvider
