Cornerstone is a high-performance, fully Native AOT-ready .NET framework that accelerates development of reliable, observable, syncable, and testable applications — without sacrificing speed or introducing reflection-based surprises.
It is the complete evolution and replacement of the Speedy framework, rebuilt from the ground up for .NET 10+ priorities: maximum performance, zero-compromise AOT compatibility, and uncompromising reliability.
- Full Native AOT compatibility — zero runtime reflection, trimmable, fast startup, tiny binaries
- Source-generation (via Cornerstone Generators):
- Binary serialization (
Packable) — fast, compact, AOT-safe alternative to BinaryFormatter/MessagePack in many cases - Automatic property change notifications (
INotifyPropertyChanging/INotifyPropertyChanged) - Source-generated reflection helpers (safe, fast metadata access)

- Binary serialization (
- Ultra-fast unit & integration testing in real AOT — tests compiled to native executable for true end-to-end validation
- Powerful deep comparison & diffing utilities (great for sync, auditing, testing)
- Built-in sync framework — reliable data synchronization across clients, services, databases
Cornerstone is built with three non-negotiable goals:
- 100% Native AOT safe — no runtime reflection, no dynamic code, no surprises
- Maximum performance — source generators + careful design = minimal overhead
- Rock-solid reliability — zero known bugs is the target
- Every feature is developed with AOT in mind from day one
- Cornerstone Generators compiles all unit, integration, performance, and automation tests into a native AOT executable
- Tests run constantly in real AOT context during development (not just JIT)
- Aim: 100% code coverage + high context coverage (edge cases, boundary conditions, threading scenarios, etc.)
- Continuous profiling to eliminate allocations and hot paths
