Referansen støtter ikke synkrone operasjoner. Parametrene for FileStream-konstruktøren må kanskje endres for å angi at referansen ble åpnet asynkront (det vil si at den ble åpnet eksplisitt for overlappende I/U).

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