Recently, I’ve been asked if Roslyn can be used for helping with writing code that involves preparing mocks with NSubstitute. Of course, my answer was "Yes" but instead of rushing into creating a new project that would implement this functionality, I performed a small research. I checked nuget.org and Visual Studio extensions marketplace, and I discovered that there was a bunch of existing analyzers and extensions that facilitated working with mocks and not only for NSubstitute but for other mocking frameworks, just like Moq or Fake It Easy, too. ...

Over a year ago I wrote a blog post about designing exceptions. I found this article very useful by myself and I used it as a reference a few times during code review. However, it’s almost impossible to expect that, after reading the recommended resource, anybody would start to apply described rules immediately and remember about them all the time. It’s a learning process and it takes some time. A while ago I got interested with Roslyn (I even delivered a public presentation about it - polish recording available here) and there is a really cool thing about Roslyn analyzers that can solve this problem - they help to actively introduce best practices into your codebase. ...

In the last few projects that I’ve attended, I was deeply involved in continuous integration. What I mean is that I was either fully in charge of setting up, configuring and maintaining CI or I was a consultant, helping other teams to deal with different problems related to this subject. All projects have been using TeamCity as a platform for continuous integration. It has a lot of predefined jobs that facilitate most common activities necessary to build pipelines, as well as rich UI that helps to easily configure it and examine pipeline results. ... Read More

In the early days of dotnet core, there was an attempt of changing the C# project file format. The old “csproj” based on XML format was replaced with .xproj/project.json. However, after releasing dotnet core 1.0 the authors decided to get back to XML file. The format stayed the same but the specification went through a major change. With the new schema, a lot of improvements come into .net development and they are not restricted only to dotnet core projects. ... Read More

It’s been over a year since I’ve started using ELK stack for logging purpose. In the meantime, I was able to successfully introduce it in a few development teams, totally changing the way we are working with application logs. Everything is working fine and the only downside so far was the need for periodical maintenance work. By maintenance, I mean removing old indices. If the disk free space drops below certain level the ElasticSearch stops working correctly. ... Read More
