O mnie Posted on Mon 11 February 2019 in .NET With many great features C# 7 comes with new and shiny pattern matching. I know that this feature is less usable then in other languages, but it add new possibilities to coding. In this article I want to share with you my experiments with monads.Optional I believe that some of you know that null exception is big pain in developer life.

Żeby sprawdzić poprawność adresu email, wcale nie trzeba męczyć się ze skomplikowanymi wyrażeniami regularnymi. W C# z pomocą przychodzi klasa MailAddress. Oczywiście jest to rozwiązanie wysokopoziomowe i wolne (rzuca wyjątki). Zapewnia jednak czytelność kodu.

[ENG] Składnia inicjalizatorów obiektów oraz kolekcji w C# (wraz z nową składnią inicjalizacji słowników z C# 6). Tekst raczej dla początkujących.

In today’s post, I’ll describe what kind of interfaces have been defined in the Sentry project, and how you can take advantage of this knowledge, e.g. in order to create the custom metrics. I’ve tried to keep these interfaces as simple as possible, yet some of them require an explanation, mostly due to the fact, that even though the library itself is rather simple to use (I want to believe that it’s also what you think), it does not mean that the main methods when being executed, will return for example,...
