Home Archive EF Core Interceptors, Agent Tooling, Identity APIs – .NET News Daily Issue #497 (Jul 15, 2026)

Editor's note

I kept this one deliberately mixed, which is usually where the most practical reading shows up. The EF Core interceptors guide stands out for its concrete .NET 10 coverage, and the Roslyn-based token budget piece is an unusually specific take on making AI-related architecture enforceable. There’s also a useful security thread here with OWASP integrity failures and custom authorization in ASP.NET.

Jasen's take on today's picks

Self-ordering modules: discovered, Kahn-ordered, and extractable

I like the use of Kahn’s algorithm here; it turns modular startup ordering from tribal knowledge into something explicit and testable.

Don’t rewrite your CLI for agents

Good corrective to the "everything must become JSON for agents" advice. Existing CLIs often need better contracts, not wholesale rewrites.

Dapr Workflow Engine: Building Durable Distributed Applications

Useful overview if you want orchestration without hand-rolling retry and recovery logic across distributed steps.

OWASP Top 10 for .NET Developers - Part 8: Preventing Software and Data Integrity Failures

A worthwhile security reminder that clean scans and passing tests do not cover supply-chain and integrity failure risks.

Delegates in C# Explained with Simple and Real Project Examples

Basic topic, but delegates still trip people up. Real examples matter more than syntax tours here.

EF Core Interceptors: The Complete Guide (.NET 10)

Interceptors are one of EF Core’s best extension points when used carefully. The audit and soft-delete examples are especially practical.

Cross-ecosystem comparisons are most helpful when they come from delivery experience rather than benchmark theater.

Why and When We Need to Use [CustomAuthorize] in ASP.NET

Custom authorization is easy to overuse, so the "when" is the important part of this discussion.

Roslyn analyzers enforcing AI architecture constraints is exactly the kind of compiler-assisted governance I want to see more of.

Building Internal AI Tools with Azure AI Foundry and .NET

Internal AI tooling is where many teams can get immediate value, assuming data boundaries and access controls are handled well.

IQueryable vs IEnumerable: The Mistake That Loads Your Whole Table

This mistake never seems to go away. Deferred execution and query translation are still core LINQ survival skills.

Broad DDD material, but still useful for readers trying to separate strategic design ideas from framework details.

Identity API Endpoints in ASP.NET Core: When to Use Them (.NET 10)

Nice practical framing: use the built-ins when they fit, and know when your requirements justify custom endpoints.

Interesting signal from Microsoft on packaging reusable capabilities for agents in a .NET-friendly way.

Multi-Tenant Saas Architecture

Multi-tenant SaaS architecture is all trade-offs; I’d read this mainly for the tenant isolation and request pipeline decisions.
