.NET się zmienia. Staje się coraz lżejszy. Minimal API są tego przykładem. Pozwalają na szybkie zbudowanie API i uruchomienie nowego serwisu. W dobie mikroserwisów i Cloud jak znalazł. Przetestowałem, jak sprawdzą się z innym wzorcem promującym prosty podział kodu: CQRS. Czytaj dalej by zobaczyć jakie są moje wnioski.

I recently migrated my VS Extension MappingGenerator (https://mappinggenerator.net/) to VisualStudio 2022. Unfortunately, I lost 4h by following the official migration guideline. Here are my notes on the subject to save you some time https://cezarypiatek.github.io/post/migrate-vsix-to-vs2022/

In the “classical unit tests” developers quite often use Arrange/Act/Assert comments to annotate the main parts of the test method script. However, the test case scenarios in component tests tend to be more complex and those simple notations don’t fit anymore. Here's my proposition on how to deal with that problem...

Czyli wróżby o tym co się wydarzy w technologii w najbliższym czasie.

Answering the question "What's the difference between a command and an event?" is not so obvious as it may seem. Fact vs Intent is not explaining everything. I went through the different aspects of this distinction in my new blog post. I also explain the consequences of those considerations.

A while ago I came across “Quick notes on a rant” authored by Don Syme. This rant criticizes the C# language for the lack of a few important features. The first point is "Implicitly discarding information is so 20th Century" which brings our attention to one of the sources of bugs in C# programs. Lucky me, I got the pleasure to make this kind of bug and find it later in production code, so this blog post is to save you the trouble...

In the last two posts, I’ve described 14 different code smells related to the async/await keywords. Beside the problem description, I’ve also provided info about code analyzers that can detect and report given issue. Those analyzers come from a few different packages that are not strictly devoted to the asynchronous programming area. They also contain rules from other fields with predefined severity, which might not be appropriate to your needs, or you might not be interested in enforcing them at all. Th...

Mocki to zmora wielu osób bo często trzeba napisać sporo „niepotrzebnego” kodu, który czasem (jeśli dobierzemy zły framework) jest zupełnie nieczytelny. Na domiar tego niektórzy używają pojęć mock, stub, fake, dummy. Jak się połapać w tym wszystkim? Co do czego użyć? Jak to wszystko pokonfigurować? I wszystko po to aby przetestować jakąś jedną funkcję… … no właśnie, dlatego nie piszę mocków. Unikam ich jak ognia. No ale jak to nie piszę? Bo jestem leniwy i uważam, że dobry...
