1>The operation to generate the project "BIOP.vcxproj" has been completed-failed.
========== Generation: 0 success, 1 failure, 0 latest, 0 skip ==========

reason:
After adding a new file on another computer or another operating system, submitting it to GitHub, and then returning to the current computer to pull the code, the new file is not imported into the VS project

Solution:
Add the newly created file to the current project, “head/source file→ \rightarrow→Add to→ \rightarrow→Existing items”
