Refactoring is the process of restructuring code to improve it. The improvements may be making the code more readable, formatting the code, or organizing it better. Refactoring shouldn’t change the behavior of code, just the quality of it. Readability is an important factor in the quality of code. If you can’t read the code, you can’t maintain it well. ReSharper helps you refactor to make your cod

Time to get excited: dotCover 2020.3 is here! Get ready for quality-of-life improvements such as coverage filtering by target framework, different build modes for continuous testing, updates to provide better coverage highlighting, command-line tooling enhancements, and more! Let's have a look. (more…)

Ah, December. A great month! It provides us with some downtime, there are a number of holidays, and it's the month where I turn 37. December also brings a chance to look back at the past year, and that's exactly what we wanted to do in this blog post: look back at our 2020 webinars, and look forward to 2021. 🤔 JetBrains Webinars? Each month, we try to bring you at least one session where c

C# 9 has brought us init-only properties and records, allowing us to work with types similarly to functional languages. Let’s take a look at some new C# 9 features and how both ReSharper and Rider 2020.3 support them. Init-only properties The ability to initialize C# objects without having to write a bunch of boilerplate code makes your code base more readable and easier to maintain. This is great

As developers, we love tools. But often, too much tooling gets in the way when trying to develop applications quickly. Have you ever been ripping through code when you want to refactor or do a common task, but just can’t find the command for it because there are too many distractions? It’s very frustrating! Let’s take a look at how ReSharper brings back simplicity when using an IDE, with its famou

With the .NET 5 release comes the newest Entity Framework Core version, unsurprisingly called Entity Framework Core 5 (EF Core 5). The .NET community got its first glimpse of Entity Framework (EF) on August 11th, 2008, with the release of .NET Framework 3.5 Service Pack 1. Let's say a few things have changed since the initial release. For those unfamiliar with the technology, Entity Framework is a

As developers, we're in a neverending struggle to find a balance between style and substance. The tabs vs. spaces argument even found its way into pop culture during Season 3 of HBO's Silicon Valley. We understand that style can be a point of debate within teams. While the codebase's style might not impact the runtime execution of applications, it can have measurable impacts on team productivity.

With the upcoming release of C# 9, we're all getting some new tools for our development toolboxes. One of the most exciting features .NET 5 is delivering to developers is top-level statements. In this post, we'll explore what top-level statements are, who they're useful for, the rules of top-level statement apps, and taking a peek at intermediate language (IL) generation. Gather round the virtual

Hello folks! With the Rider 2020.2 release out of the door, we're looking toward the future. After sharing our ReSharper 2020.3 plans earlier this week, we'll now look at our plans for Rider 2020.3. Your feedback is welcome and encouraged. The following is a set of highlighted features our team is currently working on. Let's get started. .NET 5 – Our plan is to put significant time and effort to

Today we are introducing a new type of dataflow code analysis in ReSharper and Rider. We’ve gathered some statistics (by exploring the IL metadata of a large number of NuGet.org packages with an OSS license) and noticed that int is one of the most commonly used types for local variables. That's why this new analysis tracks the usage of values of the int type in your programs. It tracks the flow o

The recording of our August 25 webinar, REST - the ignored parts, with Irina Scurtu, is now available. Subscribe to our community newsletter to receive notifications about future webinars. In a world dominated by APIs, where everyone seems to implement microservices with so many paradigms and standards to choose from, REST seems to be the default option. Despite that, many of these so-called REST

If you are already using nullable reference types, you might have noticed that they can help make your code safer. But not automagically... This feature relies heavily on everything called by your code being annotated. Unannotated APIs are a big problem for nullable reference types, as they never produce warnings. Values from such calls show extremely optimistic non-null hints, even though there a
