Handlen understøtter ikke synkrone handlinger. Parametrene til konstruktøren FileStream skal muligvis ændres for at angive, at handlen blev åbnet asynkront, dvs. at den udtrykkeligt blev åbnet for overlappende I/O.

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).
