A few years ago, I wrote about how ReSharper's Search with Pattern feature helped me refactor a massive C# codebase in minutes. The technique was powerful, but creating those custom search and replace patterns meant using ReSharper to define them. Alternatively, you could hand-craft XML in DotSettings files—tedious work that required memorizing the exact structure, generating GUIDs, and configuring placeholder properties correctly.

Recently, I explored how Agent Skills are becoming an open standard that works across different AI coding assistants like GitHub Copilot, Cursor, and JetBrains Junie. This got me thinking: what if I could combine these two powerful developer tools? What if an Agent Skill could automate the tedious part of creating ReSharper and Rider patterns?

This post shows how I built exactly that—a practical Agent Skill that generates properly formatted DotSettings XML for custom search and replace patterns in Rider and ReSharper, just by describing what you want in natural language to your AI coding assistant.

With my team, we like to keep our C# code base updated. So, recently we went to .NET 7 and C# 11. At the same time, we were still adopting some of the new capabilities of .NET 6 and C# 10. Our code base is large, so it takes some time. One of the new features that we planned to use was the ArgumentNullException.ThrowIfNull method, which throws an exception if an argument is null. In this post, I will show you how I effortlessly did that refactoring by letting the machine work and not the human 😁 (me). In the past, I used the same approach to migrate lots of code that used Assert.True() to Assert.That(, Is.True) and for some other even more complex cases. We will use ReSharper and Rider for that.

The subject of this article is the String Calculator proposed by Roy Osherove. The Kata is done in C# uses Visual Studio 2012, JetBrains Resharper 7 and NCrunch.

But what is a TDD Kata? It is an implementation exercise starting with unit tests and leveraging refactoring that you practice daily for around 15 to 30 minutes.

Finishing this week sprint I decided to inspect some code using ReSharper 6.1 EAP and I started to give ReSharper a chance to help me find some of broken code.

When I started I had some of the following inspection results. It is clearly showing that some properties wasn’t identified as used in a WPF binding.
