Parameters

• cancellationToken
  Type: System.Threading.CancellationToken

  A token whose cancelation indicates lost interest in obtaining the lock. A canceled token does not release a lock that has already been issued. If the lock isn't immediately available, a canceled token causes the code that is waiting for the lock to resume with an OperationCanceledException.

Return Value

Type: Microsoft.VisualStudio.Threading.AsyncReaderWriterLock.Awaitable
An AsyncReaderWriterLock.Awaitable whose result is the lock releaser.

.NET Framework Security
