“错误：cs0016无法写入输出文件...访问被拒绝”

我一直在努力解决这个问题。
在Web上找到一些涉及在错误消息中设置Temporary ASP.NET Files目录权限的解决方案。但即使打开Everyone也行不通。

I was struggling with this problem for a while. Found some solutions on the web that involved setting permissions on the "Temporary ASP.NET Files" directory in the error message. But even opening it up to "Everyone" didn't work.

然后最终通过以下步骤修复它：

Then eventually the following steps fixed it:

1. 转到此网站的IIS AppPool


2. 右键单击应用程序池并转到高级设置


3. 将身份从ApplicationPoolIdentity更改为NetworkService

可能还有一些其他必要步骤，我在进行故障排除时执行了这些步骤，但是这样做了是关键的一步。出于某种原因，当Everyone为时，App Pool Identity（例如IIS_APPPOOL \SiteName）未被授予访问权限。我相信其他人可以解释为什么会出现这种情况......希望这有助于其他人解决这个令人沮丧的问题。

There may also be some other necessary steps, which I did while troubleshooting, but this is the key step. For some reason the App Pool Identity (such as IIS_APPPOOL\SiteName) isn't granted access when "Everyone" is. I'm sure someone else can shed some light on why this is the case... Hopefully this helps others resolve this frustrating issue.
