Using a RegEx only within the Where statement of a linq statement is not being recognized.  The editor is saying "Warning: Remove Redundant Assignment".  Using the regex method chaining in contrast is recognized:

public void Demo ()
	// IDE is incorrectly saying this is not being used
	Regex pattern = new Regex (@"^.*\.(jpg|png)$", RegexOptions.IgnoreCase);
	string path = Path.Combine (NSBundle.MainBundle.BundlePath, "speakers");

	AddRange (from file in Directory.GetFiles (path)
	         where pattern.IsMatch (file)
	         select new Speaker { ImageFile = "speakers/" + Path.GetFileName(file) });

	// uncomment this use to see the designer stop complaining about the redundant assignment
	//AddRange (Directory.GetFiles (path).Where (pattern.IsMatch)
	//	.Select (p => new Speaker{ImageFile = "speakers/" + Path.GetFileName(p) }));
