Finally we move on to practical topics with unit tests, I encourage you to read part 2 of the Roadmap for unit tests

Dyskusje o tym jak strukturyzować nasz kod potrafią się szybko zrobić gorące. Dorzućmy więc nieco ognia do pieca! Opisałem swoje podejście do cięcia kodu, oraz opisałem dlaczego pozwala mi ono lepiej się skupić i pracować efektywnie.

Home » Foreach, IEnumerable and IEnumerator in C#Programming Today, we’re taking a deeper look at foreach loop in C#. What does a collection need to be able to use it in a foreach loop? Does it have to implement IEnumerable interface? These questions are often asked during interviews, so it’s worth knowing the answers 😃 We will go through a step-by-step example in building our own custom collection to see how all that works. Let’s dive in! 😎 Throughout this article, I’m working with a Unit Tests pro...

David August 23rd, 2021 .NET 6 is on the way, and I wanted to share some of my favorite new APIs in .NET and ASP.NET Core that you are going to love. Why are you going to love them? Well because they were directly driven by our fantastic .NET developer community! Let’s get started!Reading & Writing Files In .NET 6, there’s a new low-level API to enable reading/writing of files without using a FileStream. It also supports scatter/gather IO (multiple buffers) and overlapping reads and writes at a given...

This time I'd like to share my story about a simple bug that has grown to a serious size and what I should do to avoid it. Feel free to read!

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...

Wprowadzenie do EF Core

I gathered my notes from playing with C# records and Nullable Reference Types. Read more if you want to learn if you can use them e.g. for Value Objects or want to do Type-Driven Development.

In the previous posts in this series, I took a first look at the internal design of StringBuilder class as a linked list, and then looked at the source code behind the constructors and Append methods. In this post I look at (arguably) the most important method on StingBuilder, ToString(), and show how the final string is created from multiple chunks. I also looks at the overload ToString(startIndex, count), and show how recent implementations differ from that used in .NET Framework.Terminology recap In ...
