This is a part of a series of articles about writing a perfect console application in .net core 2. Feel free… Continue reading Perfect console application in .net Core: set up dependency injection
Why duplication isn’t always a bad thing in micro-services
From an early development age, I was taught, that duplication is a bad thing. Especially when it comes to storing data. Relational databases were invented to show data that relates to each other and be able to store them efficiently. There are even a few normalization rules, to be able to avoid data redundancy. We… Continue reading Why duplication isn’t always a bad thing in micro-services
Analyze code with NDepend
Recently I got my hands on NDepend, a static code analysis tool for .Net framework. Because it can work as a plugin for Visual Studio, it offers great integration with code and rapid results. So what it can do? Let’s see! Getting started To start working with NDepend you need to download it and install… Continue reading Analyze code with NDepend
Why sharing your DTOs as dedicated nuget package is a bad idea
I’m working in a solution, that has many micro-services and some of them share the same DTOs. Let’s say I have a Product dto, that is assembled and processed through 6 micro-services and all of them has the same contract. In my mind an idea emerged: Can I have a place to keep this contract… Continue reading Why sharing your DTOs as dedicated nuget package is a bad idea
Receive Service Bus messages in Service Fabric
This is one of the proof of concent that I did at work. The idea was to add another Service Bus application to an existing solution, instead of starting a whole new micro-service. It was a lot faster just to add another .net core console application, but setting up Service Fabric cluster always brings some unexpected… Continue reading Receive Service Bus messages in Service Fabric

I’ll show you how things are done and what are the best practices to follow. Introduction Writing unit… Continue reading Writing unit tests with NUnit and NSubstitute
Adding a log4Net provider in .net core console app
I recently was developing a console application in .net core, where I had to use log4net logging. In the standard asp.net core approach we can use:
|
1 2 3 4 |
public void Configure(IApplicationBuilder app, Microsoft.Extensions.Logging.ILoggerFactory loggerFactory) { loggerFactory.AddLog4Net(); } |
But that is asp.net core and I don’t want to reference that in my console app. In order to solve it, I had to implement my own Log4NetProvider,… Continue reading Adding a log4Net provider in .net core console app
Service Fabric Reliable Actors – is it faster then a regular micro-service approach?
Recently I’m diving into Microsoft actor model implementation – Service Fabric Reliable Actors. Apart from Microsoft Orleans, is another one worth looking into. Let’s start from the beginning. What is Service Fabric? It is many things and can be compared to Kubernetes: Simplify microservices development and application lifecycle management Reliably scale and orchestrate containers and… Continue reading Service Fabric Reliable Actors – is it faster then a regular micro-service approach?
