Why the web.config isn't copied when I publish an ASP.NET Web Project with the "Only files needed to run this application" option?

Question

How to correct it?

Answer 1

Select All project files option.

Answer 2

"Only files needed to run this application" means any build output files like DLLs and references in the bin folder and any files that have a Build Action of Content.

Since the web.config is neither of these, you'll have to change the publish option to All Project Files, or else copy the web.config manually.
