battle-tested patterns that help teams maintain large codebases
Hello! 👋
I can't believe it's almost the end of 2025. This year, I worked on the foundations and the less visible parts of the newsletter. It is back on a homebrewed self-hosted platform with improved deliverability and performance. Emails are more accessible and cleaner. And I'm following almost 1000 different authors and websites every day to find the most interesting articles.
I've put together a short survey so if you'd like to help me make the newsletter better in 2026 please fill it in. It shouldn't take more than 5 minutes. And you can participate in a $30 book voucher draw as a thank you for being an awesome reader. Here's the survey.

Enterprise patterns in real code
10 minutes by Chris Woodruff
Chris introduces a series about implementing Martin Fowler's enterprise architecture patterns in C# and .NET. Many development teams already use these patterns without realizing it, but implement them poorly. The series will explain 13 key patterns including Layered Architecture, Domain Model, Repository, and MVC with concrete C# examples. Each pattern article will show when to use it, when to avoid it, and how it connects to other patterns in real applications.
Why changing keyboard shortcuts in Visual Studio isn’t as simple as it seems
6 minutes by Mads Kristensen
Visual Studio's keyboard shortcuts are deeply tied to years of developer workflows and muscle memory. Changing a simple shortcut like Ctrl+W to close tabs is complex because it must consider multiple user profiles, keyboard schemes, scoped shortcuts, and existing sequenced commands. The team uses telemetry to see which shortcuts are used but can't determine user intent, making changes risky for established workflows.
