Editor's note
I kept this one deliberately mixed, which is how I like the newsletter best. The keyed services piece is a good reminder that useful DI features can sit unnoticed for a long time, and Damien Bod’s background tasks article stands out for showing a concrete NCronJob plus SignalR approach. There’s also a strong run of AI material here, but it’s balanced by solid app-building topics like JWT auth, S3 integration, MAUI, and background service guidance.

Jasen's take on today's picks

Keyed services still feel underused, and this is a practical nudge to revisit where named dependencies beat custom factory plumbing.
Working with AWS S3 using ASP.NET Core (.NET 10) - Upload, Download & Delete Files
Useful if you want a modern file pipeline example with presigned URLs and IAM guidance instead of just basic CRUD snippets.

Interesting angle for agent systems, though the value depends on how concretely it ties process management back to real .NET workloads.
C# 15 New Features Explained with Practical Examples
Language roundups are always worth sanity-checking, but practical examples make this more useful than a simple feature list.
Secure Multi-Tenant SaaS Development Services By Facile Technolab
More services pitch than engineering tutorial, though multi-tenant security and architecture remain relevant topics.
Building High-Performance APIs with Minimal APIs and .NET 10
Minimal APIs continue to hit a sweet spot for internal and public services where ceremony hurts more than it helps.
Building AI-Native APIs with ASP.NET Core and Natural Language Interfaces
The natural-language API angle is timely, especially when teams need to blend ASP.NET Core fundamentals with AI-facing interfaces.
Securing .net 9 Application Using JWt Refresh Token signup , login
JWT refresh token walkthroughs remain evergreen, especially for teams building their own auth flows in newer .NET versions.

Nice practical integration topic. Email is mundane until you need verification, resets, and delivery concerns done correctly.
Create Multi-platform Apps with .NET MAUI and the MAUI Community Toolkit
Good to see MAUI still getting hands-on coverage, especially when the Community Toolkit helps reduce repetitive UI plumbing.
Understanding IHostedService & BackgroundService in .NET 10
A solid comparison topic. Knowing when BackgroundService is enough and when you need a scheduler saves real production pain.
ASP.NET Core background tasks with NCronJob and SignalR
Damien Bod usually brings grounded examples, and NCronJob with SignalR makes for a useful real-time background processing combo.
Understanding SemaphoreSlim in .NET
SemaphoreSlim is one of those primitives people use before they fully understand it, so a practical guide is welcome.
Using configurable token lifetimes in Microsoft Entra ID, .NET and Microsoft Graph
Token lifetime policy details matter, especially when identity defaults collide with actual business and security requirements.
SOLID Principles in C# — Real Enterprise Examples That Actually Make Sense
SOLID lands better with enterprise examples than with abstract definitions, so this framing is the right one.
Union Types Are Finally Coming to C#
If union types truly arrive as described, they’ll clean up a lot of result modeling and exhaustive matching patterns.
Vertical Slice Architecture in ASP .NET Web API
Vertical slice architecture still resonates because it maps better to features and teams than layered abstractions often do.
Feature Flags for AI Applications: Safe Deployment Strategies in .NET
Feature flags for AI are more than rollout mechanics now; they’re becoming governance and cost-control tools too.
Building AI Agents in .NET with Microsoft Agent Framework
Worth a look if you’re evaluating Microsoft’s agent tooling and want something more concrete than high-level AI platform talk.
Top .NET Core Background Job Tools
Useful survey material for teams choosing between simple job runners and broader workflow orchestration platforms.
How Gemini Helped Me Upgrade 100+ .NET Projects in few days Instead of Weeks
Large-scale upgrade stories are interesting when they include enough specifics to separate repeatable practice from one-off luck.
