GitHub Actions

No cloud CI on PRs

MJMilan Jovanović [email protected] (Milan Jovanović) 2 d ago

Turning off PR CI: local gate with gh-signoff and a required status

Milan Jovanović describes turning off cloud CI for pull requests, running the build and tests locally, and posting a signoff commit status with the gh-signoff GitHub CLI extension. A git pre-push hook runs the gate, a GitHub ruleset requires the status before merging, and one cloud run stays on merges to main. It is a practical option for .NET teams that want to cut Actions costs and waiting time.

Who owns the clock? Lessons from a live Blazor and SignalR multiplayer game

A developer describes building a live bingo game on .NET 10, shared by a Blazor Web App and a MAUI Blazor Hybrid app over SignalR. The post covers keeping the game lifecycle on the server, using a BackgroundService to announce start times, making joins idempotent, and handling InteractiveAuto components that boot twice. It is a practical read for anyone building real-time Blazor apps.

NebulaGraph

Duplicate-free graph loads

DVDEV Community: #csharp Mehdi Mohseni 3 d ago

Idempotent NebulaGraph bulk ingestion from .NET using deterministic VIDs

NebulaGraph has no unique indexes, so duplicates in a graph load usually come from unstable vertex IDs and edge ranks. The author shows how to derive deterministic VIDs from business keys with FNV-1a and pin edge rank, which makes repeated loads safe. A batched .NET ingestion pipeline with checkpoints and retries is included.

Entra ID

Protect APIs with scopes

DVDEV Community: #dotnet Bilal Haidar 3 d ago

Securing APIs with Microsoft Entra ID: scope, client and token validation

A practical guide to protecting an API with Microsoft Entra ID: registering the API, exposing a scope, and registering the client that requests it. It walks through a .NET Core API using Microsoft.Identity.Web, a React client using MSAL, and a .NET web app calling a downstream API. The same token checks apply to any backend stack.

Events and subscriptions

Events and Delegates in C#: Contracts, Subscriptions and Notification

This article explains the difference between delegates and events in C#, the subscription boundary an event creates, and how multicast invocation behaves when a handler throws. It also covers what notification does not guarantee: completion of every subscriber, async handling and subscription lifetime. Read it to design event-based notifications with clearer contracts.

Markdown notes app on Avalonia without WebView: lessons from a C# project

A Russian developer built Leaflet, a Windows Markdown notes app in C# on Avalonia 12 with AvaloniaEdit, without WebView or Electron. Notes stay as plain .md files with wiki-style links and backlinks, and the app starts in under a second. The write-up covers live preview, browser-free PDF export and the rough edges of window decorations, caret placement and file-conflict safety.

Azure SQL

One writer, distributed design

SQAzure SQL Blog Anna Hoffman 3 d ago

Is Azure SQL Database Hyperscale really distributed SQL?

Azure SQL Database Hyperscale splits a single-writer SQL engine across separate compute, log, page server and storage tiers, so it is distributed in architecture but not in write capacity. The author explains where that line falls against the usual meaning of distributed SQL, and cites a commissioned benchmark against Aurora PostgreSQL. Useful when you choose a database for a growing workload.

Reusable review workflow

A reusable Claude Code skill for reviewing ASP.NET Core endpoint changes

Nick Cosentino explains how to package a recurring .NET review job as a project-scoped Claude Code skill. The example reviews endpoint changes across validation, authorization, response mapping and persistence, and the article stresses clear limits on what the agent may run. It is a practical starting point for teams that want repeatable AI-assisted reviews of ASP.NET Core code.

Hunt dead code with agents

NPNimblePros Blog 3 d ago

Using AI agents to clean up dead code, stale packages and feature flags

A NimblePros Halloween post walks through removing the accumulated cruft of long-lived .NET codebases: unused private members, unreferenced public types, unused or vulnerable NuGet packages and stale feature flags. The method pairs compiler analyzers and dotnet CLI checks with an AI agent that investigates edge cases, guided by a reusable skill file. It is a practical playbook for teams who never find time to clean up.

Critter Stack in Review: message loss fixes, clean shutdown and multi-tenancy

JasperFx shipped 72 tagged releases across Wolverine, Marten and shared libraries between October 12 and 30. The headline theme is a durable inbox and outbox hardening pass that closed about a dozen ways messages could go missing or run twice, much of it driven by community bug reports. For .NET developers running durable messaging, the review also covers performance fixes, cleaner shutdown and multi-tenant Marten changes.

EF Core Isn't Slow: Five Query Patterns That Are

This article outlines five EF Core query patterns behind many slow pages, plus one habit that catches them all: read the SQL EF generates instead of judging the C# code. It covers N+1 queries, loading whole tables or unneeded columns, cartesian explosions from collection Includes, and filters that prevent index use. It is a practical checklist for anyone writing data access code.
