A few days ago I’ve gave it a shot and posted a link to my project on the reddit. Amongst some positive comments, there was this one: "I would never use a library that is not documented at all". Although it was the very first version of the Sentry, a typical preview & work in progress thingy (which I did forget to mention in my post), I’ve realized that it’s high time to provide some form of documentation, otherwise why would anyone use that library, even if it was making a miracles? I thought that...

Recently I’ve had this idea that came into my mind while working on the Sentry – let the users of my library (if there will be any) to configure not only the set of rules, connection strings, urls etc. but also the underlying providers that do all of the heavy lifting (e.g. the HttpClient responsible for communicating with the API). It means that as long as you’re not satisfied with the default solution, please feel free to provide your own engine that will for example talk to the database and perform a ...

This is third post in a series about MiSeCo – a project I am working on for the “Daj się poznać challenge” (in Polish). In the last post, I wrote about the structure of a MiSeCo project and how I am going to implement the base functionality. Today I would like to show you how I managed to create my first interface implementation dynamically in runtime. Just to remind you, I need them to be able to proxy the calls between microservices through some (to be defined) protocol – probably over HTTP co...

In the third post about XGain I would like to say something about the heart of server. TcpListener is a great class to build server. It has a normal and async methods, you can choose between Socket and TcpClient. Unfortunately writing this same logic for new project might be boring.

Behavior-driven development (BDD) is a process of developing the software that has evolved from the TDD (test-driven development). We can think of a BDD such as the feature driven approach to the TDD. The main advantage of the BDD over the TDD is the way the tests are being written, in a form of the story that can be understood both by the developers and the customers. In short, we can simply state that the BDD is the TDD done right – it makes use of the so called ubiquitous language which is the core pa...

Programowanie jest powtarzalne. Nic z tym nie da się zrobić. Można jednak to nieco uprościć i zrzucić część rzeczy na dostępne na rynku biblioteki.

The new type of the watcher for the API monitoring is already available. Actually, it has much in common with the website watcher (very akin configuration, and under the hood uses the HttpClient as well), however it does serve a different purpose, which is making the request to the API and validating its response, whereas the website watcher basically pings the given url (well, it can validate its response too), and does not really care about any other HTTP method different than GET. In this POST (did yo...

Korzystając z Entity Frameworka warto zwracać uwagę na sposób pobierania danych. W przypadku, gdy nie będziemy ich modyfikować, a chcemy jedynie pobrać dane tylko do odczytu, przydatna okaże się metoda AsNoTracking(). Wywołanie metody skutkuje brakiem śledzenia danych przez kontekst. Dzięki temu nie marnujemy niepotrzebnie zasobów. Przyjrzyjmy się poniższemu przykładowi, w którym porównamy pobieranie danych z i bez metody AsNoTracking(). Na początek pobieramy dane standardowo. W tym celu modyfikujemy...

Wstrzykiwanie zależności. Porównanie kontenerów IoC i wybór najlepszego do projektu WebAPI.

.NET framework has a Socket class to deal with low-level networking. Standalone synchronous server based on Socket is not so difficult, here is an example:. Microsoft has provided two ways of creating high performance TCP/IP server. The most cool is SocketAsyncEventArgs with event-based system
