Without any more

Answer 1

Althouth there many things that could go wrong and the proper way is to actually troubleshoot the error, my case was simpler:

I forgot to configure the release output path for Swagger

You can to that by following these steps:

1. Right click your project
2. Click Properties
3. Click on the Build tab
4. And at the Output section check the XML documentation file checkbox.

This will autocomplete the path with an XML file, but you can change that to whatever you want.
