Graphs as Agent Memory: Why Vectors Alone Are Not Enough

Vector search tells your agent what looks similar; it cannot tell it what depends on what. This article shows concretely where embedding retrieval fails for dependency reasoning, then models a real service graph in NebulaGraph 3.7 with full C# wiring and traversal code.

Keeping Your Knowledge Graph Current Without a Dedicated Team

A knowledge graph that nobody updates becomes a lie with good syntax. This article builds the automated maintenance loop — deriving edges from git history, deployment manifests, and OpenTelemetry service maps, reconciling on a schedule, and handling conflicts with provenance on every edge.

Edge AI with .NET, Part 4: Time Series That Outlives the Hardware

Sensor readings are more valuable than the devices that produce them. This instalment shows how to model IoT meter data in TimescaleDB 2.29, map it with EF Core 10, and run a .NET anomaly-detection worker that survives meter swaps, tariff changes, and dead cameras.

Building an Agentic System in .NET, Part 6: Redaction, Audit and the Safety Layer

If you archive every agent session, you also archive every secret anyone ever pasted into one. This last part covers the full safety layer: redaction pipelines, audit trails, prompt injection threat modelling and retention pruning, with code.

Graph-Native Data Structures in C#, Part 6: DAGs and Dependency Graphs

Model a build system dependency graph in NebulaGraph, keep it acyclic from C# at insert time, get the execution order with Kahn's algorithm, and answer what is blocked right now. With real nGQL and C# code.

Building an Agentic System in .NET, Part 4: Keeping Memory True

Stale agent memory is not just wasteful, it causes real failures that are hard to trace. This part builds the whole defence: timestamps, decay scoring, deduplication, contradiction detection, verification on read, and scheduled pruning as .NET hosted services.

Building an Agentic System in .NET, Part 1: Anatomy of an Agent Harness

A chat wrapper is not an agent harness. This article walks through every structural component a real .NET 10 agent host needs, the turn loop, tool dispatch, persistence and the safety layer, and shows the minimal C# skeleton that survives a crash.

Vertical Slice Architecture in ASP.NET Core: Features as First-Class Citizens

Vertical Slice Architecture inverts the instinct behind layered systems. Instead of grouping code by technical concern, you group it by use case. Here is how to structure, share, test and migrate to slices in a real ASP.NET Core codebase.
