900 kilometers of German autobahn, lots of coffee and two speaker dinners was what it took to attend my second BASTA! conference and share my ideas on keeping your architecture and code in check as well as building well-documented and versioned HTTP APIs.

These are the kind of changes I completely rely on @jetbrains Junie for

It's going to be a couple of busy months...

Really impressed with @jetbrains Junie and Sonnet 4. I used the following prompt to refactor a large sequential class into a version of the Strategy Pattern. What kind of cool examples do you have while using AI tools during coding?

Just finished the slides for next week's talk on building well-documented versioned HTTP APIs in .NET. I'll cover a lot of ground and use a lot of demos to show you the following aspects of responsible design. ✅ What are important elements of a good HTTP API (cont'd)

Just a couple of days and then it's time to share my ideas on how understanding the internal boundaries of your codebase will make a lot of complexity such as the technical design, duplication, unit testing and dependency injection a lot simpler to deal with. See also basta.net/microservice...

Visual Studio 2026 Insiders is here! devblogs.microsoft.com/visualstudio... I guess it's time to update the comparison with its biggest competitor.

A lot has been said and written about that hype called #AI. It’s amazing, it’s bad, it’s dangerous — all depending on who you ask. Personally, I see it as just another tool. Granted, it’s a very smart tool, but a tool nonetheless. At least, for now… (cont’d)

The beauty of preparing a technical .NET presentation, is that it forces you to thoroughly understand the intricacies of the given technology and becomes a learning experience by itself.

Anybody has any good experience using a commercial or open-source workflow engine in .NET. We're looking at www.inngest.com, but are open to alternatives.

🎙️ Speaking at BASTA! Conference Mainz 2025! 📅Sept 22–26, 2025 📍 Mainz 🧠Topics: Boundary-Driven Development, Versioned HTTP APIs 🎟️10% off → code bas-dennis 🔗https://basta.net/mainz/tickets-mainz/?go=ok #BASTA #DotNet #CSharp #SoftwareArchitecture #BASTAConference #APIDevelopment

Pretty cool to see how @JetBrainsRider auto-completes an HTTP request using the routes registered in my solution.

I wish that Microsoft thought a bit harder about testing Azure Service Bus applications so that you can create in-memory tests without having to rely on containers.

During that same weekend, I also shipped a new version of my .NET Library Starter Kit. 1.5 includes the following improvements: (cont'd)

During the weekend, I've released version 1.5 of Pathy, a tiny open-source package for fluently building and using file and directory paths without binary dependencies. (cont'd)

My schedule for the rest of the year just got a bit fuller. Will I see you somewhere at one of those conferences?

During the weekend, I've released version 1.6 of PackageGuard, a fully open-source tool to scan the NuGet dependencies of your .NET solutions to control the open-source licenses that you want to allow or certain versions of certain packages you want to enforce or avoid. (cont'd)

We've just released Fluent Assertions 8.6 that introduces a new capability that we like to call "inline assertions". Check out the examples below or look for the release notes at www.fluentassertions.com

And here's another small release of Pathy, a tiny library for fluently building and using file and directory paths without binary NuGet dependencies. Version 1.4 ships with two nice quality-of-life features that I needed myself in another project. Check it out at github.com/dennisdoomen...

Finished the fifth book in the "Stormlight Archive". Now I have to wait years for the next 5 books to arrive. How am I going to fill this void? Any recommendations?

We’ve all been there — staring at a wall of log entries in Azure App Insights or your local console, trying to make sense of a flood of warnings, errors, and stack traces that lead… nowhere. You dig, you filter, you search, but instead of answers, you find noise. (cont’d)

PackageGuard 1.5 includes a couple of new features as well as bug fixes. - Support for .slnx format - Allow denying prerelease packages - Display the version in output log - Fix license detection of NUnit and NETStandard.Library Read more about PackageGuard at github.com/dennisdoomen...

The second half of 2025 promises to as exciting as the first half was. Can't wait to engage with the developer community all over Europe.

When building HTTP APIs, clarity is everything. Developers rely on status codes not just to confirm success, but to understand what went wrong—and what to do next. If your API can’t communicate that cleanly, you’re not just confusing clients—you’re slowing everyone down. (cont'd)

What's the most satisfying (>2000 piece) #lego set you've built recently? I'm looking for something after I finally finish the Ferrari Daytona.

I've you've been using the JetBrains Annotations NuGet package to give hints to Rider on how code is used inside and outside your codebase, there's a source-only version of that package that will help avoiding the dependency hell. See www.nuget.org/packages/Jet...

Copilot autonomously providing a GitHub pull request for a feature or issue in my open-source projects is truly amazing to see. github.com/dennisdoomen...

Last weekend, I've pushed a small improvement to Pathy, a small open-source project for fluently building and using file and directory paths without binary dependencies. Check out the read-me at github.com/dennisdoomen...

My "early access" Teams regularly stops the incoming video (as well as that of my camera) while sharing a window. It's an i7-14700K with an RTX 5080. I have to kill and restart Teams to fix this. Has anybody observed something similar.

This week, I've shipped a new version of the .NET Library Starter Kit. Version 1.4 comes with several improvements: * Employ PackageGuard 1.4's caching to speed-up license scanning * The assemblies build by the template's solution were not versioned correctly. * Minor tweaking of the .editorconfig

One of the challenges in building #PackageGuard is to extract the license information from either the GitHub repository or some other internet location. This process takes quite some time and slows down the analysis and sometimes even causes rate-limiting errors coming from GitHub.

A very nice perspective on AI tooling by GitHub that I fully support (and recognize). See github.blog/ai-and-ml/ge...

HEY! .NET DEVS!! Join the .NET team as we show off the latest features in .NET 10 Preview 6! Streaming LIVE, HERE in just a few minutes ➡️ https://msft.it/63327s61wS #dotnet #aspnet

Last weekend, we've pushed #FluentAssertions 8.5 to NuGet. It comes with a feature that we've been trying to finish for at least two years; the ability to have "BeEquivalentTo" optionally assert that the types of the objects and properties match as well. See fluentassertions.com/releases/#850

🎤 I’ve spoken at more conferences than I can count, so I’m used to big claims about scale and attendance. But as I traveled home from WeAreDevelopers World Congress in Berlin, I realized just how amazing and professional this event truly is. This one lives up to the hype.

Now even developers stuck with Azure DevOps can use AI to review their code before bothering a fellow developer, provided they use @jetbrains-rider.bsky.social

It's that time of the year again, but I'm happy to have received this email while onstage at the #WeAreDevelopers World Congress...

Join me at 16:50 at stage 4 (in Hall 2.2) to hear about principles, practices and tools I use at my professional projects and which I learned from my open-source projects.

The room is so full, people are piling up outside to get a peek of David Tielke talking about keeping your architecture flexible in the Architecture Track of the #wearedevelopers World Congress.

Here's @manfredsteyer.bsky.social talking about combining multiple versions of multiple web frameworks in the Architecture Track of the @wearedevelopers.bsky.social World Congress.

I just discovered that #WhatsApp allows me to edit my messages. Am I late to the party? #boomer

It's going to be a busy day at the "We Are Developers World Congress". In the morning, I'll be the host of the architecture track at stage 9 and then, at 16:40, I'll do my own talk on what you can learn from a .NET open-source project with more than 500 million downloads and apply at your day job.

Hmm, somehow Microsoft decided that my primary Edge profile needed a reset and reconnect me with Bing. Now I can't find anything anymore...

🎤 The Developer World - DWX is a wrap. After having spoken at this unique conference in Nuremberg since 2017, it was a refreshing experience to speak at their new venue in Mannheim (and less of a drive to get there)...

This is awesome news, especially with Fluent Assertions 8.5 around the corner. And don't forget, version 8 remains totally free for all open-source repositories.

As developers, we rely on source control not just to track changes, but to collaborate, refactor, and release with confidence. Yet some of the most popular source control systems weren’t built for how modern teams actually work today. It’s time to expect more from your tools. (cont'd)

In case you missed it, during the last couple of days, we've released Fluent Assertions 8.4, Reflectify 1.6 and NET Library Starter Kit version 1.3.0.

Last week, I started to try @jetbrains-rider.bsky.social built-in AI functionality to make large-scale code changes. I'm seriously impressed how well it managed to make significant code changes based on my (sometimes) broad requests.
