One of the wonderful things about .NET is the vast array of platforms .NET developers can target. My personal experience has been developing ASP.NET applications and HTTP APIs, but recently I've been dabbling with mobile applications built using Rider and Xamarin.Forms. For those curious, or maybe even a little scared, about working with Xamarin.Forms, well, don't be. I've found the Xamarin.Forms community to be welcoming and very helpful to a mobile newbie like me. I've also found the platform itself to be straightforward to get started and iterate on as I've learned new approaches to solving

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

Hello everyone, Welcome to the early access program of our third release of the year, Rider 2020.3. The highlights of the first EAP build include more advanced C# 9 support, new debugger features, and UX improvements. Let’s look into the details. UX improvements The most obvious update is the redesigned Welcome screen. More is less: we’ve tried to make the first window you see in Rider as neat and uncluttered as possible. It offers only the most common operations. A long-awaited improvement has made it into the code editor: now you can split the editor by dragging and dropping

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

The recording of our webinar, Xamarin, MAUI and the reactive MVVM between them, with Rodney Littles, II, is now available. Subscribe to our community newsletter to receive notifications about future webinars. Xamarin Forms is the .NET cross platform technology that allows you to write an application in C# and target various operating systems, primarily mobile. The recommended architectural approach for .NET applications adhering to SOLID principles is Model-View-ViewModel (MVVM). ReactiveUI is a MVVM framework based on Reactive Extensions, which are a cross language approach to functional pro

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 support the upcoming release of .NET 5. While development is possible in Rider today with .NET 5, it is incomplete. .NET 5 is the future of .NET, and we want to help developers get there. More Perform

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

We all need to unit test our code to verify that it works the way it’s supposed to. Fortunately, Rider has the tools to enable you to test code more efficiently and quickly. In this post, we’ll look at using Mocha and Chai to write unit tests in TypeScript. (more…)

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
