.NEXT (dotNext) is a set of powerful libraries aimed to improve development productivity and extend .NET API with unique features. Some of these features are planned in future releases of .NET platform but already implemented in the library:

Proposal Implementation
Interop between function pointer and delegate DelegateHelpers factory methods
Check if an instance of T is default(T) IsDefault() method
Expression Trees covering additional language constructs, e.g. foreach, await, patterns, multi-line lambda expressions Metaprogramming
Async Locks Documentation
High-performance general purpose Write-Ahead Log Persistent Log
Memory-mapped file as Memory<byte> MemoryMappedFileExtensions
Memory-mapped file as ReadOnlySequence<byte> ReadOnlySequenceAccessor
A dictionary where the keys are represented by generic arguments Documentation
Process asynchronous tasks as they complete Documentation
Soft References Documentation

Quick overview of additional features:

All these things are implemented in 100% managed code on top of existing .NET API.
