我尝试了所有上述补救措施和建议。这些都不适用于我的环境。根据微软的说法(在 Microsoft connect 的错误 id 781048 下),他们尚未为 MVC/Razor 文件实现 CSS 类智能感知,但正在努力将其包含在未来的版本中。
我有一个 10 分钟的扩展 VS2012 智能感知的网络广播示例,它添加了一种解决方案,可以将智能感知添加到您的 VS2012 环境:Visual Studio Intellisense 扩展
网络广播使用 MEF 扩展 Visual Studio 以添加智能感知完成源,该源扫描当前加载的项目以查找 CSS 类名称以添加为智能感知完成集。这是css完成源类:
