Where do logs go when running ASP.NET Core on IIS 7.5?

You must make sure the log folder exists! IIS won't make it for you. Such a simple solution to this infuriating problem.

You could probably check the Event Viewer on your machine -> Application to see if there are any errors logged, which could explain why your log files aren't being generated.

However, the most probable reason is that IIS doesn't have a permission to write to that log folder.

1. Right click on the folder -> Security
2. Ensure that IIS_IUSRS user has the following permissions: read and execute, list, write (potentially write is missing by default)
