One of the great features of .NET is that you can mix its programming languages (C#, F#, VB.NET) in a single solution and that assemblies written in one language can call assemblies written in other languages. This is great, especially when starting with F#. A team does not need to switch everything at once, but can keep using the existing C# code and use Interop to call C# from F# or vice versa.In this article, we take a look at the Interop story in 2026. Spoilers: it works great.
In our product, I sometimes encounter the problem of dynamic IN-lists in SQL. First, they appear harmless, but soon they lead to an unnecessary amount of query plans. In this blog post I share how to circumvent those issues with TVP. A clean, performant and reusable way to solve this problem!
Not having to annotate types for every argument and return value in F# is a big relief. In this blog post, I share some tips and tricks to reduce the need for type annotations.
Scrum, SAFe and Co., with their sprints, backlogs and masters, are now well known to us. It’s time to explore some of the latest developments.
We store most of our application’s data in an SQL server database. Sometimes, we need to transfer the data locally to debug defects related to production data. The database grows daily, and restoring the database locally takes more and more time. So we had the idea to disable indices because they are not needed for debugging locally, but restoring them takes quite a lot of time. We can’t disable indices before exporting the data to a bacpac file because it’s the productive...
Yesterday evening, I gave a workshop titled “To test, or not to test” at the Software Crafters Zürich Meetup. In the workshop, we gathered reasons to write tests: being confident that the code works, being confident that regressions can be prevented, helping to drive the implementation, and having documentation of the system. Interestingly, when I prepared the workshop, I forgot about the documentation aspect of the tests. Here is why and why it matters.

I didn’t find a way to “compress” the talk, so there is a loooot of text. A good talk, but not well suited for a sketchnote. 😅
