Depending on how the TaskItem is created, the ItemSpec may be a relative path so it may be better to use the full path of each item using this approach:

var path = item.GetMetadata ("FullPath");

Obviously we can do this outside the loop for asm as an optimization.

My other suggestion is that we may want to use an OrdinalIgnoreCase compare since the Mac file system is case insensitive by default.
