Zdaję sobie sprawę, że temat dzisiejszego wpisu zdecydowanie nie wygląda „PRO” i wydawać by się mogło, że przeznaczony jest dla absolutnych laików programowania. Myślę jednak, że wielu programistów zaczynających swoją przygodę z mikroserwisami zadaje sobie w duchu pytanie, w jaki sposób ustrukturyzować wszystkie projekty i pliki, aby miało to ręce i nogi. Cóż… ja przynajmniej tak miałem i po kilku próbach + dyskusjach z innymi programistami wypracowałem własny „przepis”, który uwaga – dla mnie działa. Ni...

In the previous article, we started analyzing asynchronous programming in .NET world. There we made concerns about how this concept is somewhat misunderstood even though it has been around for more than six years, ie. since .NET 4.5. Using this programming style it is easier to write responsive applications that do asynchronous, non-blocking I/O operations. This is done by using async/await operators.  However, this concept is often misused. In this article, we will go through s...

In the previous article, we had a chance to look at the basics of machine learning and we got introduced to the way ML.NET framework is working. For that purpose, we have used Iris Dataset, which is a very basic classification problem. Let’s take up a notch and try to solve something which is a bit more advanced. In this article, we will see how we can apply same concepts from the previous article on one regression p...

RyuJIT is the code name for the .NET just-in-time compiler, one of the foundational components of the .NET runtime. In contrast, the Roslyn C# compiler compiles C# code to IL byte code. The RyuJIT compiler compiles IL byte code to machine code for multiple processors. With the recent merge of the dotnet/coreclr #18064 pull request, the...

Wstrzykiwanie zależności z wykorzystaniem kontenerów jest bardzo wygodne, ale też niesie z sobą trochę problemów. Jednym z tych problemów jest ilość oraz moment tworzenia obiektów. W tym wpisie pokaże ten problem oraz zaproponuje swoje rozwiązanie z wykorzystaniem obiektów Lazy. Poniżej jest przedstawiona dość standardowy kawałek kodu aplikacji ASP.NET MVC, w której jest wykorzystane wstrzykiwanie zależności przez konstruktor w formie interfejsów. Jak widać na kodzie pow...
