VSTS build Copy Files task copies full path to destination

Worthwhile to mention it helps if you use BuildConfiguration variable so it doesn't break when you use a different build config:

So it turns out I just needed to change my source directory to the folder where the binaries were.

NOTE This only works because I know exactly where the desired files are. If you find this and you're trying to copy from multiple directories, you have a couple options:

1. Multiple Copy Files tasks
2. Just deal with the extra directories.

Advanced => check Flatten Folders or flattenFolders: true in the YAML file.

I'm guessing this option didn't exist back then.
