[ROOT] how to create a file on Castor with v3.10.02

I would like to create a file on castor with ROOT, but my usual method to 
do that does not work anymore with the version 3.10.02 of ROOT (on lxplus, 
my ROOTSYS is /afs/cern.ch/sw/root/v3.10.02/rh73_gcc2952/root ).

below a simple example :

void start()
  TFile *F=TFile::Open("rfio:/castor/cern.ch/user/l/lechowsk/test.root", 
  TH1F *H=new TH1F("h","h",100,-5,5);

With 3.5.05 this works, but with 3.10.02 I have the message " 
stage_updc_filcp " several times. The file has been created on castor (the 
Open works), but has 0 octets (the Close doesn't work).

Do you know something about that ? Has something changed ?
I see that now there is TCastorFile, I tried it but ROOT doesn't know it :
Error: Symbol TCastorFile is not defined in current scope
How could I use it ?

Thank you.
