Referansen støtter ikke asynkrone operasjoner. Parametrene til FileStream-konstruktøren må kanskje endres for å vise at at referansen ble åpnet synkront (det vil si at den ikke ble åpnet for overlappende I/U).

Handle does not support asynchronous operations. The parameters to the FileStream constructor may need to be changed to indicate that the handle was opened synchronously (that is, it was not opened for overlapped I/O).
