George Wall - production-safety tooling for .NET teams

ConfigContraband HttpClient Resilience Analyzers LinqContraband DI analyzers AOEOverlay

Signal

I build production-safety tooling for .NET teams: Roslyn analysers, developer workflows, and focused utilities that catch expensive mistakes before they ship.

The thread running through my work is simple: make the failure visible while the developer is still in the editor, keep the diagnostic precise enough to trust, and ship the fix with tests, docs, and release automation.

Featured Systems

Analysers and Safety Tooling

Project Focus Why it matters
automapper-analyser Mapping safety Moves AutoMapper configuration failures from runtime surprises into compile-time feedback.
CancelCop.Analyzer CancellationToken discipline Keeps cancellation flowing through public APIs, handlers, EF Core, HTTP calls, and Minimal APIs.
ConfigContraband Configuration correctness Catches broken appsettings, missing sections, duplicate JSON members, and option-shape drift before runtime.
DependencyInjection.Lifetime.Analyzers Dependency injection lifetimes Detects captive dependencies, unsafe scopes, and lifetime mismatches that usually fail late.
HttpClient.Resilience.Analyzers Outbound HTTP resilience Flags unsafe HttpClient usage and resilience gaps before transient failures become production incidents.
LinqContraband EF Core and LINQ safety Flags query shapes that cause client-side evaluation, N+1s, cartesian explosions, and costly production behaviour.

Developer Utilities

Project Focus Why it matters
CPMigrate Package management Helps .NET solutions move to Central Package Management with dependency health checks and rollback.

Desktop Apps

Project Focus Why it matters
AOEOverlay Tauri desktop overlay A TypeScript/React/Tauri app that shows I also build polished local desktop tooling, not just compiler analysers.

Toolbox

.NET C Sharp Roslyn ASP.NET Core EF Core TypeScript React Tauri Swift Rust Python

Current Bias

  • High-signal analysers over noisy rule volume.
  • Runtime failures converted into compile-time feedback.
  • Developer-facing diagnostics that explain the fix, not just the failure.
  • Small packages that are documented, tested, versioned, and releasable.

Working Style

I like boring reliability, fast feedback, clean diagnostics, and tools that pay for themselves the first time they stop a bad deploy.
