Ok. Not sure where to start from.
So, A .NET Core WinForms app was packaged with a Windows Package Project but after installation of the app, it throws an exception when trying to start app, as is shown below in the image.
Such file (appsettings.json) should be in installation directory as it's supposed to be copied always into the output directory when building the app, and in fact, it's being copied but I think it's something related to the Windows Packaging Project.
Not sure how to solve this issue.
Best regards!
