Web Push Notifications in .NET 10 with VAPID
W3C Web Push lets the browser ring even when your tab is closed. With VAPID you do it without FCM, without APNs, and without a single US-hosted dependency. Here is the .NET 10 side, the React hook, and the 30 lines of service worker that ties them together.
Building an Import Pipeline: CSV and Excel with Validation

HTML-to-PDF in .NET: PuppeteerSharp + Scriban Without the Pain

Adding Authentication with Keycloak in Granit
Wire Keycloak JWT Bearer authentication into a Granit API in five minutes — claims transformation, role mapping, back-channel logout, and an Admin authorization policy, all from one DependsOn.
5 EF Core Mistakes That Kill Performance
