今天在阿里云虚拟机上部署新站点后出现下面的错误：

Compiler Error Message: CS0016: Could not write to output file 'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\xx' -- 'Access is denied. '

找遍了网上的资料最后总结为以下几步：:

• Cleaned the "C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files" folder
• Gave Full permissions to IIS_IUSRS group
• Gave Full permissions to "Everone"
• Ran the following command too: %windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis -i

郁闷的是都没能解决我的问题，最后给 "C:\Windows\Temp"文件夹加上 IIS_IUSRS的权限就好了。
