Architecture, AI, and ASP.NET Core Production
Curated .NET coverage: architecture patterns, ASP.NET Core identity, AI/MAUI edge computing, multi-tenant SaaS, EF Core auditing, and agentic frameworks.
Jasen's top three picks
- 1 The .NET Architecture Pattern That Impresses in Code Reviews — but Can Break Under Real-World Scale
medium.com
Clean architecture looks great in code reviews but can crumble under real load—a sobering reality check.
- 2 Lost ASP.NET Identity Cookies on IIS Application Pool Restarts
weblog.west-wind.com
IIS application pool restarts silently nuking session cookies is a gotcha that still catches teams migrating to .NET 10.
- 3 Taking your AI to the edge with .NET MAUI
youtube.com
MAUI + local AI models = edge computing without cloud dependency; practical for offline-first mobile apps.
Editor's note
This week’s mix spans architecture philosophy (DRY misunderstandings, design patterns as rituals), production troubleshooting (IIS cookie loss, request length limits), and the AI wave reshaping .NET development. Entry 1 on architecture patterns and entry 2 on IIS cookie loss caught my eye—both are real pain points teams face after launch, not just in theory.
