The DLL Registration Trap in Legacy .NET Framework Applications
If you’ve ever worked on a traditional .NET Framework application — the kind that predates .NET Core and .NET 5+ — this story may feel painfully familiar. I’m talking about classic .NET Framework 4.x applications (4.0, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1,...
ConfigureAwait(false): Why It Exists, What It Solves, and When Context Is the Real Bug
Async bugs in C# are often context bugs. ConfigureAwait(false) doesn’t magically fix deadlocks, but it limits the damage when async code is blocked. This article explains context capture, blast radius, and a real production incident where the true fix was using the correct framework synchronization context.
Structured RAG for Unknown and Mixed Languages
This article shows how naïve RAG fails on multilingual activity streams and why structure is the real fix. By extracting stable metadata into a JSON schema at write time, RAG becomes predictable again. Structured RAG trades extra processing for accuracy, debuggability, and reliable retrieval across mixed and unknown languages.
RAG with PostgreSQL and C# (pros and cons)
This article was born from a real failure while applying RAG to an activity stream. Multilingual, unstructured user content broke naïve retrieval. The experience exposed how fragile RAG can be without structure, language awareness, and disciplined pipelines—lessons learned only after deploying RAG in a real system.
Accessing Legacy Data (Fox pro) with XPO Using a Custom ODBC Provider
Accessing legacy data doesn’t require rewriting old systems. This article explains how XPO and ODBC can be combined to integrate FoxPro, AS400, and DB2 databases into modern .NET architectures, enabling the use of Blazor, .NET MAUI, and even AI agents while respecting legacy dialects and type systems.
ODBC: A Standard That Was Never Truly Neutral
ODBC has been connecting applications to databases for decades. From FoxPro’s all-in-one world to modern .NET systems, this article explores what ODBC really is, why it still matters, and how it helps reduce database dependencies while improving portability and long-term maintainability in enterprise software.
