.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 a default(T) IsDefault() method
Concept Types Documentation
Expression Trees covering additional language constructs, i.e. 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

Quick overview of additional features:

All these things are implemented in 100% managed code on top of existing .NET API without modifications of Roslyn compiler or CoreFX libraries.
