I keep getting this error when publishing files. It does not matter if its to a local directory or URL server. The project builds correctly, and I can run the application. I have administrator rights to all locations. I've tried to delete bin an obj directories but same errors.

Any ideas at what is causing this ???

    CAUSE: Destination file path too long.
    RESOLUTION: Moved public location closer to root of drive (shortening destination paths).

    I experienced this issue and figured out that for me, the resulting path for the file being copied ended up being too long and exceeded Windows 11 allowance. I then attempted to address issue by changing OS configuration to accept longer paths through Group Policy Editor, rebooted, and publish still failed, but now with a "file not found" error, instead of the previous "could not find part of the path". I then moved the publish location to a folder closer to the root of the drive (thereby shortening resulting paths, and this then produced a successful publish completion.
