NonBlocking 2.1.2

dotnet add package NonBlocking --version 2.1.2                
NuGet\Install-Package NonBlocking -Version 2.1.2                
This command is intended to be used within the Package Manager Console in Visual Studio, as it uses the NuGet module's version of Install-Package.
<PackageReference Include="NonBlocking" Version="2.1.2" />

#r "nuget: NonBlocking, 2.1.2"                
#r directive can be used in F# Interactive and Polyglot Notebooks. Copy this into the interactive tool or source code of the script to reference the package.

Implementation of a lock-free dictionary on .Net

     Included types:
     === NonBlocking.ConcurrentDictionary
     Lock-free, wait-free implementation of a dictionary.
     - has the same API as System.Collections.Concurrent.ConcurrentDictionary.
     - No locks are taken during any operation including Get, Add, Remove, internal resizes etc...
     - While multiple threads accessing NonBlocking dictionary will help each other in operations such as table resizing, there is no dependency on such behavior. If any thread get unscheduled or delayed for whatever reason, other threads will be able to make progress independently.
     - NonBlocking dictionary scales linearly with the number of active threads if hardware permits.

     On most operations NonBlocking dictionary is faster than Concurrent, especially in write-heavy scenarios.

     Core algorithms are based on NonBlockingHashMap, written and released to the public domain by Dr. Cliff Click. A good overview could be found here:

     === Counter32
     === Counter64
     Low-overhead scalable counters.

The fastest cache library written in C# for items with set expiration time. Easy to use, thread-safe and light on memory. Optimized to scale from dozens to millions of items. Features lock-free reads and writes, allocation-free reads and automatic eviction. Credit to Vladimir Sadov for his implementation of NonBlocking.ConcurrentDictionary which is used as an underlying store.
