Compile-time DI auto-registration for .NET via a Roslyn source generator. Zero reflection, no assembly scanning, AOT/trimming friendly.

Source-only toolkit for authoring Roslyn source generators: equatable arrays, an indented code writer, C# naming/casing helpers, hint-name sanitization, cache-safe diagnostic descriptions, and a diagnostic... More information

Error-code-based domain exceptions: a side-effect-free ErrorCodedException base, static guard clauses that capture the caller's expression text, and a compile-time generated exception-to-code mapping table with... More information

A thin, framework-agnostic test harness for incremental source generators and analyzers: runs a generator over in-memory source, asserts the generated code recompiles cleanly, asserts diagnostics by... More information

Deterministic, state-serializable PRNG (xoshiro256** + SplitMix64) with a unified random-source abstraction and weighted-random sampling. Zero dependencies.

Deterministic, serializable time-state calculations: calendar recurrence boundaries (daily/weekly/monthly), half-open time-window arithmetic, elapsed-time cooldown/recharge state with O(1) offline catch-up, and... More information

Opt-in compile-time diagnostics for non-deterministic APIs (ambient clock, process randomness, Guid.NewGuid, randomized hashing, environment identity, scheduling) inside [Deterministic] scopes, with concrete... More information

Platform- and process-independent 64-bit checksums via a version-locked canonical encoding contract (XxHash64). Zero dependencies.

Time-zone-aware recurring reset boundaries (daily/weekly/monthly) over TimeProvider: previous/next boundary, current window, crossing detection and crossing counts, plus a half-open TimeWindow value type. The... More information
