在IIS上托管.net Core 2.1拒绝访问解决方案路径？

Question

我在开发服务器上设置了.net核心2.1 Web API，它工作得很好，但是当我尝试在实时服务器上浏览站点时，出现以下错误：

Unhandled Exception: System.UnauthorizedAccessException: Access to the path 'R:\SoftCatWebApi\ETL' is denied.

我尝试分配不同的内容，我将具有所有权限的应用程序池应用于该文件夹，并且启用了匿名身份验证。

我确实在不同的论坛上尝试了多个建议，但没有任何缝隙可以解决我的问题。

有什么建议吗？

如果我从CMD运行dll，我会得到一个不同的错误：

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime, Version=4.2.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

更新：

如果我单击IIS管理器中的任何选项，则会出现web.config错误

似乎，您的应用程序池标识没有访问路径的权限。 只是要确保，请具有权限的用户更改池标识。
