Looking forward to next week in Oslo. I'm doing both a workshop and a talk. But most important is all the old and new friends I look forward to meeting.

Excuse me @expressense.bsky.social, but that is not an Oresjnik missile. Missiles usually do not have a bunch of people attached. I'd love to hear the story about how that image ended up inte article. Maybe some kind of modern automatic tooling? www.expressen.se/nyheter/varl...

@jonskeet.uk I know you worked hard on the multi-version doc site for Noda Time. I've been prototyping a site that automatically generates docs for any package on Nuget to make it more convenient to publish docs. It's available at nudoc.net. Would love to hear your opinions if this could be useful.

Duende Software's legendary training on Identity and Access Management was originally created by Dominick Baier and Brock Allen. We're offering the training online/remotely as 6 half-day blocks in EU afternoons/US mornings, starting March 10. Read more and sign up at sustainsys.com/training

I released some new features to NuDoc.NET. It's mostly support for generics and improved cross-linking. I think it's now at a point where it's starting to be usable and not just a proof of concept. The next step is to handle tags inside the docs: paragraphs, lists and resolving links.

I took some time over the holidays to hack on an idea of a documentation for .NET solutions. There are so many things that can be done, but the first step is to make what already exists available: NuDoc.NET creates cross-linked reference docs for any package on Nuget.org nudoc.net/Docs/Sustain...

Writing documentation tends to be pushed to the bottom of the todo list. With C# we got XML comments that promised automatic reference documentation, but it's rarely used and it provides no solution for high level docs. What would your dream solution look like? (I might be working on something).

Current Status: "We do these things not because they are easy, but because we thought they were going to be easy." Why did NuGet ever allow a version on the format Maj.Min.Patch.Other? (system.net.http version 2.0.20126.16343)

Starting the new year with a new blog post: coding.abel.nu/2026/01/net-... It's been years since last time I had inspiration to write anything. Don't take this a s a promise for the rest of the year though.

@kevlin.bsky.social Parking payment in Stockholm. To be fair, it's a new system that is not yet operational.
