The Multi-Result-Set Dream EF Core Wouldn't Grant
An entire stored-procedure framework built on an EF6 extension library, shipped inside an EF Core app, in a folder named Future - the anatomy of an abandoned migration and how to recognise one.

Gap-Filling Two Years of Attendance
The shift calculator writes one report row per employee per day since 2019, inventing blank rows for days nobody badged - a dense date spine built from sentinel values, at the price of one database round-trip per row.
Three Ways to Call a Stored Procedure
Reflection that builds EXEC statements, a table-valued function called by string interpolation, and a raw ADO.NET runner returning lists of lists - one codebase, three coexisting answers to the same question.
Guessing Your Shift with Manhattan Distance
Badge gates record when you arrived, not which shift you worked - so the platform infers it, scoring every candidate shift by L1 distance in time-of-day space and letting the smallest number win.
A DB-First Model in Code-First Clothing
A decimal surrogate key beside the natural key that does the work, scaffolded index cruft with a placeholder name, a DbSet of List of string, and lazy proxies in a projection minefield.
When a Cancelled Leave Rewrites Last Month
Leave records arrive late, change and get cancelled - so the sync reaches back into already-approved attendance rows and re-derives them, carefully stepping around human decisions and allowance money.
Resurrecting Html.Action in ASP.NET Core
MVC5 child actions were removed from ASP.NET Core, so this codebase re-implemented them - an ActionContext conjured mid-request, a MemoryStream response swap, and a .Result at the heart of 118 call sites.
A Watermark Made of Your Own Success Log
The leave sync resumes from wherever its own job log last said Success - one table serving as log, watermark and metrics store at once, with recursive pagination on top and an envelope check in exactly the wrong place.
Compiling Authorization Out of Debug Builds
Every controller wrapped its Authorize attribute in
Syncing the Org Chart at Midnight
A daily Azure Function mirrors the HR system's employee master into the attendance database - a field-by-field upsert, a clever delegation rule, a vestigial handshake, and the parse calls that can kill the whole run.
Logging In with CAS When Everyone Uses OAuth
A 2004-vintage SSO protocol wired into ASP.NET Core - ticket validation, roles derived from the database at login time, and single sign-out through a WordPress front door.
The Database Is the Message Bus
Five executables, zero queues - how an attendance platform coordinated a web app, three Azure Functions and a console job through one SQL database, and what that choice bought and cost. Part 1 of the series.
An Attendance Platform in ASP.NET Core
Badge gates, WFH timers and shift allowances - the shape of a seven-project intranet attendance platform, the onion it almost is, and the roadmap for fourteen more parts.
