Use of ReaderWriterLockSlim

[fredericoregateiro]

Hi,
I'm learning TCP and this project has helped me a lot, thanks for sharing this project.

I have 1 quertion regarding the usage of ReaderWriterLockSlim in ClientMetadataManager, this class uses several Dictionary<Guid, DateTime> to keep track of the clients and is there any reason to not use the built in ConcurrentDictionary<TKey, TValue> instead of both ReaderWriterLockSlim and Dictionary<TKey, TValue>?

Thanks
