) : AsyncReaderWriterLock.Awaitable
Parameters
options
Type: Microsoft.VisualStudio.Threading.AsyncReaderWriterLock.LockFlagsModifications to normal lock behavior.
cancellationToken
Type: System.Threading.CancellationTokenA 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.
