【问题描述】：
我遇到了 Intellisense 无法完全使用 C# 的问题。对于某些事情它确实有效（例如：尝试使用 using 语句），而对于其他事情它不起作用（例如：Linq 查询或在 startup.cs 文件中 app.{enter whatever} 什么都不显示）。但对于我的其他同学来说，它确实为他们展示了所有这些。 Omnisharp 的绿色火焰表示服务器正在运行并且我的语言设置为 C#。抱歉，我不完全知道提供 Omnisharp 日志的最佳方式，它太大而无法截图，而且我是第一次发帖。编辑：当某些东西不起作用时，也没有任何下划线，我不知道这是否有帮助，但我也注意到我的其他同学在使用 VS 代码时会发生这种情况

我不太确定 OmniSharp 是什么，但根据此处输出的错误，您的项目文件似乎有问题；这可能会固有地导致您的智能感知出现一些问题。
InvalidProjectFileException是编译器试图告诉你你的 .csproj 文件在某种程度上是无效的。您的代码是否在某种版本控制系统中，您可以恢复到项目的先前版本和/或查看发生了什么变化？ -
即使我创建一个新文件夹并为其执行 dotnet new mvc，智能感知问题仍然存在。
-
我对此的完全理解充其量是模糊的，但我阅读了几次警告和错误，最后我发现（这里有一些真正的技术术语）无论是在寻找omnisharp 还是 intellisense或者任何决定这些东西在 Visual Studio 2017 中的东西。我卸载了 Visual Studio 2017 并重新安装了 VS 代码的 C# 扩展，现在它可以工作了
