Software Architecture

Design error handling in C# pipelines with typed results, exception boundaries, short-circuiting, cancellation, idempotency, retry ownership, and tracing.

Combining C# specifications with AND, OR, and NOT requires Boolean laws, explicit null policies, parameter rebinding, and EF Core relational provider tests.

Build correct async pipelines in C# with sequential awaits, propagated cancellation, observed tasks, explicit completion ownership, and safe async disposal.

Use the Specification Pattern with EF Core DbContext queries while keeping tracking, result limits, cancellation, SQL checks, and relational tests explicit.

Build a type-safe C# pipeline from scratch with generic stage contracts, heterogeneous transitions, immutable messages, and compiler-checked composition.

Build a dependency-free C# specification pattern example with immutable named rules, an explicit null policy, focused tests, and balanced design tradeoffs.
