.NEXT

.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:

Quick overview of additional features:

• Attachment of user data to an arbitrary objects
• Extended set of atomic operations. Inspired by AtomicInteger and friends from Java
• Fast Reflection
• Fast conversion of bytes to hexadecimal representation and vice versa with Hex class
• ManualResetEvent, ReaderWriterLockSlim and other synchronization primitives now have their asynchronous versions
• Atomic memory access operations for arbitrary value types including enums
• PipeExtensions provides high-level I/O operations for pipelines such as string encoding and decoding
• A rich set of high-performance memory buffers for efficient I/O
• String formatting, encoding and decoding with low GC pressure: dynamic char buffers
• Fully-featured Raft implementation
• Fully-featured HyParView implementation

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

Release & Support Policy

The libraries are versioned according with Semantic Versioning 2.0.

❌ - unsupported, ✅ - bug and security fixes only, ✔️ - active development

Development Process

Philosophy of development process:

1. All libraries in .NEXT family are available for the wide range of .NET runtimes: Mono, .NET, Blazor
2. Compatibility with R2R/AOT compiler should be checked for every release
3. Minimize set of dependencies
4. Provide high-quality documentation
5. Stay cross-platform
6. Provide benchmarks

Users

.NEXT is used by several companies in their projects:
