Minimal Example Program
Ensure /tmp/test does not exist. Run the following program:
public static void Main (string args)
var path = "/tmp/test/multifolder/relativepath/not_this_folder";
path = Path.Combine (path, "..");
Expected result (as seen on Windows with adjusted paths):
The folder /tmp/test/multifolder/relativepath/ has been created
The folder /tmp/test/multifolder has been created and the following exception is thrown:
System.IO.DirectoryNotFoundException: Could not find a part of the path "/tmp/test/multifolder/relativepath/not_this_folder/.."
