## Blog posts
- [A personal note: I built a running App for iOS and watchOS](https://steven-giesel.com/blogPost/38a0d0f4-e9ff-4947-a05c-527af68b6cd1/a-personal-note-i-built-a-running-app-for-ios-and-watchos.md): Since some time I had an issue with my running app, as more and more stuff was locked behind a monthly paywall. Plus certain things were missing, so I created my own: taperwise.
- [If It Quacks - Part 2](https://steven-giesel.com/blogPost/41599817-4457-441e-b874-1a5c67f4e7cc/if-it-quacks-part-2.md): Some days ago I wrote about duck-typing in C# with interceptors. Back then it was a proof-of-concept with a lot of rough edges. Now it is a real library: IfItQuacks.
- [Quack Quack: Duck-Typing in C# with Interceptors](https://steven-giesel.com/blogPost/5170e165-29e8-437a-b5ce-446a84943809/quack-quack-ducktyping-in-c-with-interceptors.md): If it walks like a duck and it quacks like a duck - it is a duck.

- [Adding Properties with extension methods in C# 14](https://steven-giesel.com/blogPost/4368fcea-c922-403e-bb3b-6b4990eb36d2/adding-properties-with-extension-methods-in-c-14.md): Thanks to @toupswork for starting a funny discussion about extension properties on a recent post I made: "Adding static getter thanks to extensions". Therefore let's discuss two ridiculous ideas to add properties to existing types using extension methods in C# 14.
- [Claude Memory Admin](https://steven-giesel.com/blogPost/b26c70f8-c11e-4b2b-81ad-54088ed674cf/claude-memory-admin.md): I vibe-coded a small tool to get a grasp on your projects MEMORY.md that is in ~/.claude.
- [xUnit.v3 4.0.0 released](https://steven-giesel.com/blogPost/b0e1aadf-8e88-4553-9636-19df43b1b068/xunitv3-400-released.md): xUnit.v3 got a new major release. This blog post is more about the consequences of that for your local build and CI/CD pipelines than about the new features.
- [.NET Toolbox August Update](https://steven-giesel.com/blogPost/5adbbd4f-8979-4e97-9797-2e1f05ad19b2/net-toolbox-august-update.md): Quite some time passed since I posted a changelog to the .NET Toolbox. And there are big news: The Toolbox is running dotnet native in the browser thanks to wasm and Mono!
- [.NET 11 Performance Edition](https://steven-giesel.com/blogPost/86620358-bb91-4295-84fc-a1329b2567ae/net-11-performance-edition.md): As always my yearly take on the latest .NET release. In a few months dotnet 11 will be released and I wanted to have a look into some performance metrics.
- [Adding static getter thanks to extensions](https://steven-giesel.com/blogPost/605274d2-719b-4b1f-b0d5-3ad9001d9b56/adding-static-getter-thanks-to-extensions.md): Here a simple scenario: You have a StringComparer and you want to add your own comparer to the mix - for example a "natural sort" order, so "file2" sorts before "file10" instead of a

What verification unlocks
See how your site is discovered—and control what agents see.
- See your website in the map
Review your indexed topics, nearby publishers sharing headings, measured listing exposure and map snapshots in a private report for your website.

Edit your listing description, tags, public contact details and additional llms.txt paths. Publish your terms for automated access, attribution and pricing.
- Make your profile eligible for search
A valid, listed, unblocked, verified profile can appear in our publisher sitemap and become eligible for search-engine visibility. Search engines decide what to index and rank.
- Appear in our llms-full.txt
Eligible verified publishers are listed by name, with their file links and summaries, in the service overview agents can read.
Free. No account registration, backlink or payment required. Public discovery remains available without verification.

Claim my listing on Agent Web Map for steven-giesel.com:
1. POST https://agentwebmap.com/v1/sites/steven-giesel.com/claims and keep claim_id and claim_secret private.
