In the last two posts, I’ve described 14 different code smells related to the async/await keywords. Beside the problem description, I’ve also provided info about code analyzers that can detect and report given issue. Those analyzers come from a few different packages that are not strictly devoted to the asynchronous programming area. They also contain rules from other fields with predefined severity, which might not be appropriate to your needs, or you might not be interested in enforcing them at all. ... Read More


This blog post continues the series which is a guide through the code analyzers available on the market and their possibilities. I’m trying to help you answer the question: “Which analyzer package should I use and how to configure it to avoid problems related to async/await?". In the previous episode, I presented the first seven most common code smells related to asynchronous programming. Today, I present the next seven traps from this area. ... Read More


Roslyn analyzers are great. Not only do they detect different issues in our code, but they are also able to propose solutions, thanks to accompanying code fixes. There’s one more, less-advertised aspect of analyzers: besides improving the quality of our codebase, they also improve the state of language knowledge in our teams. This is a real time-saver during the code review because the technical, language-related remarks are reported automatically in design/build time. ... Read More


There’s a certain set of special method signatures in C# which have particular support on the language level. Methods with those signatures allow for using a special syntax which has several benefits. For example, we can use them to simplify our code or create DSL to express a solution to our domain-specific problem in a much cleaner way. I came across those methods in different places, so I decided to create a blog post to summarize all my discoveries on this subject. ... Read More


A few weeks ago I started using non-nullable reference types - a new C# language feature which was shipped with version 8.0. It wasn’t a completely new experience for me, because I was working before on projects that were heavily utilizing [NotNull] and [CanBeNull] Resharper annotations. The way how non-nullable types are handled by Roslyn seems to be a little more complex in comparison to Resharper - there are around 40 different diagnostics related to this area. ... Read More
