Thanks very much but I have another question raised by your answers: 
method->slot seems to hold the actual slot number, but that value 
is not set in mono_get_method_from_token, called from mono_get_method_full 
which is invoked in method_to_ir at CEE_CALLVIRT. Where and when gets the 
slot entry of a method set? 
 
Thanks a lot for your help
