Your AI reads 14 .cs files to find one method caller. 18,000 tokens. And still misses some.
I built an MCP server that answers the same question in 85 tokens.

@iammukeshm The HasData trap is real —nothing quite like a 200-line migration just to update a seed value.
One nuance I’d add: manual idempotency in UseSeeding is harder than it looks. It deserves more than a bullet point — one wrong AnyAsync() and you’re debugging duplicate records in prod.

🚫 Ne retournez jamais vos entités EF Core depuis une API.
Fuites de données, références circulaires, N+1 & couplage au schéma ne sont pas des bugs, mais des conséquences.
✅ Responses explicites = contrat stable & API plus sûre.

🚫 Never return your EF Core entities from an API.
Data leaks, circular refs, N+1 queries & schema coupling are not bugs - they’re consequences.
✅ Use explicit Response records. Stable contract, safer APIs.

Ne comptez plus sur les devs pour le RGPD. 🛑

Granit l'intègre par défaut dans .NET via ses contraintes (intercepteurs, filtres) : soft-deletes, chiffrement, audits.

La conformité devient automatique. 🔒
#dotnet #RGPD

[Jean-François Meyers @meyersjf]

Granit enforces GDPR by design in .NET.
It uses framework constraints (interceptors, query filters, strict registries) for soft-deletes, encryption, and audit trails.

Compliance is default. 🔒

90% of .NET apps don't need microservices on day 1. Yet teams waste months on infra instead of features.
Why we built Granit as a Modular Monolith, and how to extract services later without rewriting 👇 https://t.co/rrY5ETTMCr #dotnet #csharp #softwarearchitecture

[Jean-François Meyers @meyersjf]

One framework, total architectural freedom.
Discover how @Granit_FX enables you to switch between Modular Monolith and Microservices without the usual headaches.

@XiRi0N Non, c'est pas vrai...
