Troubleshooting

After a full day’s work, realized that the source of the problem is that I had backed up one of the source code files before editing it.

Unfortunately, the backup file was placed in a folder underneath the project’s working directory.

Remediation

To correct please do one of the following :-

1. Move the folders and files outside of the project’s working directory
2. Explicitly exclude the folder or file from the project

 

Visual Studio .Net Project

Outline

1. Choose the folders or files to exclude
   • Right click on your selection
   • From the drop-down menu, please choose Exclude
