有时它有效,但有时它永远不会从它返回.我无法确定原因.我使用Visual Studio 2015和Windows 7.

这是Universal CRT的TH1版本(10.0.10240)中的一个错误.该错误已在Windows 10 November Update(TH2)版本(10.0.10586)中修复.

您可以从https://dev.windows.com/en-us/downloads/windows-10-sdk下载并安装更新的Windows 10 SDK.此SDK包含静态通用CRT库,调试通用CRT DLL(ucrtbased.dll等),以及用于应用程序本地重新分发的零售通用CRT DLL.

您可以从https://www.microsoft.com/en-us/download/details.aspx?id=50410下载更新的Universal CRT可再发行组件.这些组件包含更新的零售Universal CRT,用于在系统目录中进行集中部署.
