.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: 08-29-2026
- All
FromPointerstatic extension methods for delegates are marked with RequiresDynamicCodeAttribute, because delegate construction from a method pointer is not supported in AOT

| 6.x | .NET 10 | ✔️ |
❌ - unsupported, ✅ - bug and security fixes only, ✔️ - active development
Philosophy of development process:
- All libraries in .NEXT family are available for various .NET form factors: Mono, WASM, NativeAOT
- Minimal set of dependencies
- Provide high-quality documentation
- Stay cross-platform
- Provide benchmarks
