File timestamp in NETMF

Hi all,
I would like to check file timestamp in my application but it seems that it is not possible in NETMF. I have tried File.GetLastWriteTime() and also FileInfo.LastWriteTime and it seems that it is not possible under NETMF or am I wrong? Is there any other possibility how to check last write time of the specific file placed on SD card?

@ mhstr -

use FileInfo class, I think

@ Dat - I had to be blind. :wall:
Thanks.
