【问题描述】：

好的，所以我正在尝试学习 C++ 并想使用 Visual Studio 2013，一切都适用于 C#。

为了更容易理解，我基本上是这样做的：https://msdn.microsoft.com/en-us/library/bb384843.aspx 在第 4 步之后，它应该创建解决方案并打开文档，它会循环回到第一步，然后有时会出现正常错误windows 错误窗口。如果我尝试从文件夹中打开解决方案，它也会出错。所以它（通常）会创建文件、文件夹和解决方案，但会出错。

我宁愿不重新安装它，但这是我唯一能想到的。

我认为我没有遗漏任何明显的东西，基本上只是按照 MSDN 链接告诉我的去做，但遇到了错误。

您的代码不完整，因为我猜这就是您遇到很多错误的原因，要解决此问题，请确保您的代码与此类似：（将其复制并粘贴到您的 .CPP 文件中）

感谢您的回复，虽然这是一个很好的回复，但我实际上遇到了 Visual Studio 本身循环的问题。我最终只是重新安装，这似乎解决了它。抱歉，回复晚了！
