Hi!
I just used the refactor function "Move selection into a new file".
I selected a complete class, that was inside a namespace x.
The new file was created nut the code section was created without the Namespace.
Old:
namespace x
{
 // class to extract
 class xyz
 {
  ...
 } 
...
}
The code was extracted into the new file 
#pragma once
// class to extract
class xyz
{
 ...
} 
If possible namespaces should be kept for the selection.
Thanks for you great product.
