[c#] Couldn't process file resx due to its being in the Internet or Restricted zone or having the mark of the web on the file

If you are using OneDrive, or any similar network drive, you have 2 options:

1) the easy one is to move the folder to a local directory inside your PC (eg:. C:).

2) but if you want to keep using OneDrive I would recommend to add it to the trusted sites on the internet explorer options and that will fix the problem.
