在Visual Studio 2017社区版中有这个相同的问题。由于你的问题出现在谷歌，但没有答案，我想我会加入它。

我发现Process Explorer来自Sysinternals帮了我一大堆。

打开sysinternals并转到查找 - >查找句柄或DLL ...或（Ctrl + F）并搜索保持打开的文件。在我的情况下“System.IO.FileSystem.dll”

搜索结果显示两个MSBuild实例和一个VBCSCompiler挂在文件上。最糟糕的情况是，我刚刚杀死了进程树，建立了这个项目，一切都恢复得很好。

我有同样的问题，我与Visual Studio 2017年社区应用在我的情况下，溶液简单，我只是删除了目录的bin（C里面的所有文件：\项目\ DotNet \ ApplicationName \ bin）和我重新编译应用程序后。

我希望它能帮助你。

如果您尝试发布asp.net web应用程序在Azure和得到上面的错误然后尝试更新Microsoft.CodeDom.Providers.DotNetCompilerPlatform包V1.0.7或更高版本。最初，在您的应用程序中，会出现Microsoft.CodeDom.Providers.DotNetCompilerPlatform 1.0.5版，然后卸载，然后安装最新版本V1.0.7或更高版本的。清理您的解决方案并构建。现在，您将能够使用Visual Studio 2017在Azure中发布您的Web应用程序。
