rename - does not work for directories

File.Move(fromPath, toPath);

public override bool Rename(string fromPath, string toPath, StreamRenameOptions options, StreamContext context)
{
    try
    {
        File.Move(fromPath, toPath);
        return true;
    }
    ...
}

This breaks PHP compatibility because File.Move() cannot move directories.
In PHP, rename() works for both files and directories and does not require distinguishing between them.

.NET requires different APIs:
File.Move() → files only
Directory.Move() → directories only
