Patterns, gotchas and small wins from fifteen-odd years of .NET and web work — the Regira packages and modules, entity pipelines, editorial front-ends and everything between.
A small tool that copies files between local disks, network shares and cloud storage, where a new copy job is a config entry, not new code. Built on one storage abstraction, so adding a backend is one small class.
Keep file storage behind one interface and let each environment choose disk, network share or Azure in configuration. Tests run without cloud credentials, and moving your files later is a copy job, not a rewrite. Uploads are typed by the server, so none can pose as a page of your site.
