Are you having issues installing ReSharper in the last few days? Does the ReSharper installer complain that it doesn't find any zones exactly matching 15.something? If this is what you're seeing, then get ReSharper Ultimate 2017.1.3. Looks like that the latest Visual Studio 2017 Preview (15.3) has changed its internal versioning, which affected stable Visual Studio versions installed on the same machine, which ReSharper had no way of being aware of. With this ReSharper update, the problem should be gone. Other than a fix to the installer issues, there's essentially nothing else in th

We've got a new bug-fix update for you: please welcome ReSharper Ultimate 2017.1.2. ReSharper adds 70+ fixes. This includes a set of unit test runner fixes: the runner now correctly runs the entire session instead of just running the current selection (RSRP-464189); test output is correctly displayed when running xUnit-based .NET Core tests in Visual Studio 2015 (RSRP-464330); and the runner learns to detect and run NUnit-based tests written in F#. Another substantial group of fixes addresses TypeScript support issues, such as false red code in imported code and other contex

We have a bug-fix update for you as ReSharper Ultimate 2017.1.1 is now available for download. You should definitely get this release if you have installed the latest Visual Studio 2017 update (April 6), and then when you tried to run your MSTest suite, you saw ReSharper telling you this: Turns out that the latest Visual Studio update reverted a prior API change in a way that we didn't expect, which kind of explains why ReSharper took the absolute latest Visual Studio build for an outdated one. The problem is now fixed, and you can run your MSTest suites again. Apart from fixing t

As you may remember, along with ReSharper 2016.3 we released a special plugin entitled "ReSharper Tutorials." In brief, it's a plugin with a set of interactive ReSharper tutorials. Here's how it works: When you launch a tutorial, a sample solution is loaded. The tutorial guides you through a number of steps, each illustrating a particular feature. The plugin automatically checks whether you have performed the actions described at each step. As we released ReSharper 2017.1, the plugin also got updated to version 0.9.9. What's in this update?

This year's first major release of ReSharper Ultimate is finally here with an ultimate support for Visual Studio 2017! We invite you to download the 2017.1 update and check all the long-awaited features, which you can read about in this post. Along with 600+ fixes in ReSharper and 110+ fixes in ReSharper C++ this release comes with the following major improvements: Visual Studio 2017 support C# 7 support: local functions and throw expressions .NET Core Unit testing in Visual Studio 2017 EditorConfig support (for all languages) and other code style improvements Enhancements to na

We have finally set the release date: ReSharper Ultimate 2017.1 will be out on April 3rd. In the meantime, we are releasing one more EAP build which fixes critical issues with discovering and running unit tests. The previous EAP introduced an unfortunate bug that caused problems in discovering xUnit tests. You definitely couldn't run MSTest tests if you installed the recent Visual Studio 2017 update (as of March 28th) as Microsoft had changed APIs. Now we support only the latest update. In earlier Visual Studio versions, you'll see the following message box when trying to run unit tests:

As we approach the release date, there's always an urge to get more bugs fixed and new features polished. Obviously, we couldn't resist and decided to publish an additional pre-release build. Download ReSharper Ultimate 2017.1 EAP 7 and check some nice new features and improvements we have introduced. Throughout this Early Access Program, we’ve been working on improving the design and usability of ReSharper's Code Cleanup. This feature is useful when you need to apply a number of code cleanup tasks in a bulk mode. You can create various code cleanup profiles to apply in different scenarios.

Today we welcome you to download our last pre-release build of ReSharper Ultimate 2017.1 and check out all new features and improvements that we've been working on since the beginning of this year. In the previous builds we fixed important bugs and added new features that mostly relate to perfecting support for Visual Studio 2017 RTM and C# 7. Today's EAP build includes noticeable updates to dotMemory, dotPeek and a few other improvements that we are going to cover in this post. (more…)

We are getting closer to the release date and working hard towards providing the finest coding experience to Visual Studio 2017 RTM users. If you are already using the latest release of Visual Studio, make sure to download ReSharper Ultimate 2017.1 EAP 5 to get the best support for its new features. We have introduced quite a lot of improvements during this EAP, and today we'll take a look at updates in our two latest EAP builds. (more…)

We've just released the third Early Access Preview build of ReSharper Ultimate 2017.1. Let's take a look at the recent changes in this and EAP 2. TypeScript and JavaScript This build introduces a number of performance fixes for TypeScript and JavaScript, as our processing of file dependencies has been rewritten and optimised, wildcards in tsconfig are handled better, and the Rename refactoring for local symbols is also faster, with the ability to disable search for dynamic usage of TypeScript symbols in JavaScript files via a checkbox in the Rename dialog.

In this post, we're going to look at how ReSharper 2016.3 can help you unit test your .NET Core applications and libraries. Sadly, before we can look at this, we have to deal with the confusing issue of what versions of .NET Core are supported. TL;DR: ReSharper 2016.3 works with .NET Core projects in Visual Studio 2015 and Visual Studio 2017 "RC", but unit testing only works in project.json based projects. The IDE interface to dotnet test was rewritten for the .csproj based projects in Visual Studio 2017 "RC" and only just documented. More details at the end of this post. Unit testing i

When we released ReSharper 2016.3 (and earlier this week, ReSharper 2017.1 EAP), we introduced initial support for C# 7 and VB.NET 15. For example, ReSharper now understands binary literals and digit separators, as well as local functions with several inspections. We're far from feature complete, but want to look ahead at what's coming in terms of new programming language features and what we are working on for ReSharper (including some of the challenges building out those features). Here goes!
