C# VS代码2017-C“错误”；有些项目在加载时遇到问题。请查看输出以了解更多详细信息”；

因此，我安装了C#扩展和.Net以及其他所有工具。根据Internet上的教程，我有一个工作区。。。还做了一些其他的事情，比如在终端中输入一些dotnet命令。一切正常，没有问题，但每当我打开脚本/文件。。。最初创建的程序-Program.cs包含默认的“Hello World！”程序。。。然后，它会显示一条错误消息，表示无法加载项目。不过，当我在终端中编写dotnet run时，它的输出没有任何问题

我在互联网上见过很多这样的帖子，但还没有一个对我有用。我只是不知道出了什么问题。这就是为什么我在这里问这个问题，并把错误信息放在这里。。。这样我就能知道我的案子出了什么问题。因为我是VS代码的新手。。。也不知道到底出了什么问题

下面是显示在“输出”选项卡中的错误消息-

相反，如果我试着运行这个程序，我会在输出中得到它-

operable program or batch file.

将vs代码设置中的

omnisharp.path

设置为

latest

• 转到设置->搜索

  omnisharp.path

  ->单击设置中的

  编辑.json

• 在settings.json中，向下滚动到最后一个设置，添加逗号，然后添加“omnisharp.path”：“latest”->保存文件并重新启动vs代码以安装最新的omnisharp（带有修复程序）

因此，根据该线程，这意味着我需要将Visual Studio升级到最新版本，即2019，以便使C#能够在VS代码上工作？或者如果我想继续使用Visual Studio 2017，请将.Net降级到以前的版本？谢谢。在我偶然发现这个答案之前，我到处寻找这个问题的解决方案。这个答案不适用于vscode 1.48.2——最新的omnisharp:1.37.2-beta.2。这个问题也破坏了我的laravel工作区（它们被认为是c，颜色是错误的），幸运的是这个解决方案解决了它
