It was always surprising to me that so few projects were started with data access concurrency in mind. I’ve heard many discussions about new fancy frameworks and UI controls the teams were about to use but possibility of concurrent access to users’ data didn’t appear to be a concern in their minds. Wen you think about it, it seems to be very logical. People have a natural tendency to avoid problems they haven’t encountered directly. There are so few people with attitude of challenging o...

Wakacje, wakacje i po wakacjach. I bardzo dobrze, ile można, c’nie? Po wakacyjnej przerwie powracamy, zamaszyście, pomału i usłużnie. Ale suchy rebus! Mału -> mikru -> mikro. Usłużnie -> serwisowo -> service. Czyli: po wakacyjnej przerwie powracamy, zamaszyście, z mikroserwisami! Towarzyszy mi Michał Franc, który z dalekiego jUKeja wskoczył mi na Skype’a. Michał bloguje na http://www.mfranc.com, przemawia oraz jest jednym z organizatorów konferencji dotnetconf.pl. Na Twitterze możecie go stalkować pod @...

In this post we’ll focus on security. We’ll try to prove that claims base authentication is safe. As we remember SAML tokens are issued by “trusted” STS. But what exactly does “trusted” issuer mean? In this post, we’ll try to find definition of “trusted issuer”, a list of attributes which decide that issuer is trusted.

In this article we focus on sample service based on WCF (Windows Communication Foundation), as we will only try to build sample service with claims-based authentication and authorization. All technical aspects connected with security e.g. configuration, certificates, encryption, signature or CRL will be described in details in the next posts.

W ASP.NET w końcu !!! w końcu !!! nie ma pliku csproj! Czy tam vbproj czy nawet SLN… Ja! :) no fajnie nie? :) Teraz wszystko działa wokół project.json file, który jest definicją naszego projektu jak i! definicją paczki nuget. Czyli jak się domyślacie referencje teraz pomiędzy projektami to referencje za pomocą paczek nuget…

Kestrel to serwer webowy umożliwiający hostowanie aplikacji .NET na różnych środowiskach w tym Linux i Mac._ Pamiętacie komendy z poprzedniego postu? Jeżeli chcemy hostować aplikację webową (której jeszcze nie mamy i pewnie w tym poście też jej mieć nie będziemy ;)) na wszystkich możliwych platformach to musimy lekko zmodyfikować nasz projekt dodając odpowiednie zależności i tworząc nową komendę. Komenda ta będzie p...

I have started to think, what is the reason that people see it as hard and complex at the beginning? I have a theory: it has rules! Entering the world with rules is always uncomfortable, we need to adjust to rules. In this post I’d like to prove that in this case those rules are quite digestible.On the way to CQRS… Basically, we can say that CQRS is an implementation of Command Query Separation principle to the architecture of software. What I noticed during my work in this approach is that there is a c...

ASP.NET MVC 6 supports both regular controllers (inheriting from Controller base type) and POCO controllers. Let’s have a look at how the discovery of them happens in ASP.NET MVC 6. Note that the code and mechanisms discussed in this article were introduced after ASP.NET 5 beta3 was released, so it is not yet available if you use the version of ASP.NET 5 bundled with Visual Studio 2015 CTP6.

TL;DR 1. Define events in the system Define sources (commands, process managers) and actors Group commands around aggregates Implement… Post-it, long piece of paper and people…Let’s play Generally speaking „event storming” is about extracting domain from events which describe it. In most of the complex domains there are events that represent important changes in the state of our domain, simply begin with them. We’ll need the following things:Unlimited modelling space – sounds impossibl...

Microsoft is a massive software corporation, and like all other corporations, they’re in business to make money. Duh, right? Unfortunately, this is probably the #1 reason for all the ASP.NET hate: it’s a Microsoft technology, and the “evil” taint still lingers over the giant in many people’s minds. I’ve always found this interesting because the other major technology companies, such as Google and Apple, are just as “evil” as Microsoft, but the zealots fans of those other companies typically turn a blind ...
