.NEXT (dotNext) is a set of powerful libraries designed for high-performance scenarios when your application expects near zero memory allocation and high flexibility. It is aimed to high-load microservices, database engines, actors, and various types of distributed applications. The feature list includes a rich set of efficient tools with low overhead:
- Buffer manipulations
- String building
- Monadic types
- Advanced GC notifications
- Low-level API to work with memory: alignment detection, type-safe unmanaged allocators, Span<T> manipulations
- Base64 streaming encoder/decoder
- Async-friendly SIEVE cache
- Async locks
- Extended LINQ Expression Trees and dynamic code generation tools with async lambdas for metaprogramming
- Raft Consensus Algorithm with extensions such as the failure detection
- Fast general-purpose Write Ahead Log
- TCP multiplexing protocol
- HyParView protocol implementation
All these things are implemented in 100% managed code on top of existing .NET API.
Release Date: 09-05-2026
FromPointermigrated from handwritten IL code to fast reflection using UnsafeAccessor, which is more portable across .NET versions

- Optimized catch up of the temporary unavailable node when it becomes available again for the leader. Outdated leader now can report last WAL index, so the leader can adjust replication position for the node much faster than just decrementing it speculatively in every replication round
- Added stricter control for the order of state machine recovery and WAL initialization
