I get the following error when I try to publish.

@lordlycastle, Thanks for the question! We are taking a look into this and will get back to you soon.

@lordlycastle,
I tried to repro your scenario and I was able to publish without any issues.

As I was unable to repro your scenario, I was wondering if have you tried creating the directory manually in the bin/debug directory ?

If you tried creating it manually, that might be why you are seeing this error because you need to created the directory path from inside the code and see if that helps.

Also take a look at this doc for more reference : DirectoryNotFoundExceptionClass

I hope this information helps.

Please feel free to revert back with any questions you might have regarding this matter.
