Remarks

ReaderWriterLock is used to synchronize access to a resource. At any given time, it allows either concurrent read access for multiple threads, or write access for a single thread. In a situation where a resource is changed infrequently, a ReaderWriterLock provides better throughput than a simple one-at-a-time lock, such as Monitor.

If a platform does not support a System.Threading.ReaderWriterLock implementation then all readers and writers are serialized. Therefore the caller must not rely on multiple simultaneous readers.
