Hello everyone, Please welcome ReSharper 2020.3 EAP1. It’s only the beginning of the release cycle, but we’ve already got something to show you! ReSharper With C# 9 on the way, we’re doing a lot to support the latest language standard. For top-level statements, ReSharper not only provides some basics, like code completion and code analysis, but also offers a couple of handy quick-fixes and refactorings. When copy-pasting pieces of code, we often don't care about placement. However, C# 9 requires top-level statements to precede any type or namespace declarations. Fortunately, ReSharper

Dear everyone, Today is bug-fix day! We’ve addressed several issues in both ReSharper and Rider and published the ReSharper 2020.2.3 and Rider 2020.2.3 builds. ReSharper 2020.2.3  ReSharper no longer freezes Visual Studio when the Favorite Documents extension is installed (RSRP-481224). Now you have more precise control over which Visual Studio actions can be overridden by ReSharper on the ReSharper | Options | Environment | Keyboard | Visual Studio Commands page. Rider 2020.2.3  Breakpoint icons no longer disappear from the code editor (RIDER-48535). There are a few fixes in F# support relat

In this post, we’d like to share our plans for ReSharper 2020.3 and find out what we can do next to improve your development experience. Your feedback is always welcome! The following is a list of our priorities for the next release cycle of 2020.3. Note that these are features we’re working on – as opposed to features scheduled for delivery. Some of these might come with later versions. .NET and C# – Support for new platform and language features, like top-level statements or target-typed new expressions. We will extend our support for nullable reference types (NRT), for instance with a dedi

New bug-fix updates are available for both ReSharper and Rider. Here’s an overview of the most important changes that have been made. ReSharper 2020.2.2 Fixed a couple of false positives in nullable analysis. Fixed the default implementation of an interface from a referenced package. It is now recognized correctly (RSRP-480835). Fixed the 'Current directory' for unit tests. It is now set to the test project's 'bin' directory. Other unit testing issues that have been fixed are described below in the Rider section. The rest of the issues and details are available in ReSharper's bug tracker. Ri

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 of integer values through your programs to detect useless or possibly erroneous pieces of code. It warns you about the following issues: Relational/equality operators that always evaluate to true or f

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 APIs don’t respect the guidelines and become brittle by overlooking some of the most powerful constraints. In this session, we will look over how we can design a REST API that is flexible and evolvab

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 are no guarantees that these hints are correct. Here's a compiler issue for this problem. For example, if you are using LINQ's FirstOrDefault() method from .NET Core 3.1, the compiler not only allows y

As you may know, our .NET and Visual Studio tools got a massive 2020.2 update just a few weeks ago – the ReSharper .NET tools, ReSharper C++ and Rider blogs have more details. Now our sights are set on the 2020.3 release due out at the end of this year. But before we get back to work on that, we have one more important thing to say. We are deeply grateful to all participants of our 2020.2 Early Access Program. You helped us identify countless issues, usability glitches, and missing features. Thank you so much! We’d like to share our special thanks with these fine folks who have been the most a

We’ve just published two hotfix updates, Rider 2020.2.1 and ReSharper 2020.2.1. Here are the highlights of what we’ve introduced. For the full list of changes, please refer to our bug tracker. Rider 2020.2.1 NuGet We’ve fixed the bug that caused all NuGet packages to be restored unnecessarily before building the project (RIDER-49125). Unit testing NUnit2 tests are no longer left in an Inconclusive state with System.NullReferenceException (RSRP-480840). The option to run NUnit tests from a specified folder now works correctly (RIDER-49367). The appsettings.json file is read correctly when ru

Hello everyone, Today we’re excited to give you ReSharper 2020.2! This major release introduces new inspections and quick-fixes for C# 8, most notably for nullable reference types, a much-awaited Code Cleanup on Save, a revamped Unit Test Runner, and various accessibility improvements. Download ReSharper 2020.2 Since the ReSharper license now covers both ReSharper and ReSharper C++, support for C++/CLI – a bridge between the languages – is getting a lot of updates and improved interoperability between C++/CLI and C#. Read through the major updates of all the JetBrains .NET tools and extension

With each passing day, the .NET ecosystem introduces new target environments. In addition to Windows environments, we can now deploy to Linux, macOS, and all popular mobile operating systems. Having these options is excellent, as it allows us to reach a broader audience, but each new environment comes with its own set of challenges. .NET Framework has solved the multiple-environments issue by creating the .NET Standard. The .NET Standard exposes a common API we can compile against with the understanding that our target environments have a context-specific implementation. In this post, we'll se

We’re often asked how ReSharper and Rider relate to build servers, and how their features can be utilized in CI/CD environments. There are actually quite a few tools bundled in free packages – namely ReSharper.CommandLineTools or dotCover.CommandLineTools – that can help to continuously monitor and improve our codebase. In this post, we will discuss the ReSharper tools, which include: InspectCode – runs code analysis to find and report code issues DupFinder – identifies semantically duplicated code fragments CleanupCode – reformats code to make it consistent Check out our blog po

The recording of our July 9 webinar, How to stop worrying and adopt nullable reference types - Webinar Recording, with Andrey Dyatlov, is now available. Subscribe to our community newsletter to receive notifications about future webinars. Nullable reference types is a deceptively simple feature.
