We have many solutions for versioning data through time. One of the cleanest, most transparent and pretty effortless in my opinion are Temporal Tables which are available in MS SQL 2016+. What’s really great about that approach is that unless you need to retrieve state from the certain point in time or browse through changes in a specified time range, you can query against a versioned table in an exactly same way that you would do with any other one.

I finished work on my presentation about “CQRS in 4 steps” which will be shown during Wrocław .NET meetup and KGD .NET meetup. You can find slides from my presentation on Slideshare, Moreover, there are sources on Github and I encourage you to go through the below materials.

Prowadzę blog już ponad dwa lata, piszę regularnie – trochę treści się nazbierało przez ten czas. Postanowiłem stworzyć z wyselekcjonowanych wpisów ebooka i udostępnić go za darmo wszystkim zainteresowanym. Jest to pilotażowy projekt – chcę zobaczyć czy będzie cieszył się zainteresowaniem. Myślę, że ebook może ci się przydać m.in. w sytuacji, gdy nie jesteś na bieżąco z moimi wpisami i chcesz je nadrobić będąc np offline lub preferując czy...

I really enjoy learning new architectures, design patterns, frameworks, libraries or in general – everything related to web development. I really do. But honestly, after quite long time all these stuff became a little bit… boring. To avoid possible burnout I decided to play with something completely different. My thoughts circled around functional programming (F#, Heskel), IoT, quantum programming in Q# and much more, but none of them felt right. Enlightenment ...

Zachęcam do oglądnięcia mojego Lightning Talka pod tytułem "Nic nie wiem". Opowiedziałem jak moje doświadczenie w projektach pokazało, że warto mniej wiedzieć i zakładać a więcej pytać i starać się zrozumieć czego chce od nas klient.

W ostatni weekend(23-24.09.2017) odbyło się Devstyle Speakers. Były to dwudniowe warsztaty z występów publicznych i prowadzenia prezentacji. Było świetnie! Po więcej zapraszam na najnowszy wpis na moim blogu.

A while ago I wrote about creating Actor System and top-level actors. Sadly it was stored in a static field. And keyword static is … let’s say it’s not one of my favourites. Today I’ll show you how I’m doing the exact same thing but in Dependency Injection container.

When I’m writing this there are still 2 and a half hour to the end of “Get Noticed 2017 contest. Let’s wrap everything up. The basic goal was to develop open source project and blog about this at least 2 times a week. I did a post about my project when I’ve released first alpha/beta version of it, you can read it here.

I'm sure that you heard about .NET Standard. To simplify the definition just one quote from the offical GitHub repo FAQ .NET Standard is a specification that represents a set of APIs that all .NET platforms have to implement. This unifies the .NET platforms and prevents future fragmentation. BTW in case you don't know just read the full article Introducing .NET Standard. On the other hand, Owin is (from owin.org): OWIN defines a standard interface between .NET web servers and web applications. The ...

While I can’t say casting is a way to go in C#, it’s a rather common operation. It’s good to know there is more than one way of doing that and the best way depends on current circumstances. Explicit Cast I’m assuming you know what casting is but just to be clear, I mean changing object type like casting an int to long or some kind of JSON to string. It’s common, it happens all the time and sometimes we just need to do that. Let’s start with the most basic case of explicit casting.
