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! In this post: Digit separators and binary literals Local functions Output variables C#

If you are a long-term user of dotTrace Timeline Viewer, you've likely noticed some UI changes in dotTrace 2016.3. What has changed exactly and, more importantly, why were these changes made? Read on to find out. (more…)

ReSharper offers hundreds of quick-fixes and context actions. As you remember, quick-fixes are aimed to resolve a certain problem in your code, whereas context actions allow you to quickly introduce some minor changes. Today we are going to review several quick-fixes and context actions that simplify your work with method parameters in C#. Some of them have been available for years, some have only been added in the most recent release. (more…)

ReSharper's code generation actions can create a lot of code for us. Why manually write a constructor that initializes type members? Why manually implement interface methods and properties? ReSharper can do those things for us! Some say developers who use tools to generate code are lazy. Personally, I like to call that efficient. Instead of writing code that is, in essence, programming language ceremony, we can let ReSharper generate it for us and focus on implementing business value and solving our customer's problem instead. In this post, we'll go over some of the newly introduced and upd

We are starting the new year with a bugfix update for ReSharper Ultimate 2016.3. All in all, it addresses 50+ issues in ReSharper, dotCover, dotTrace and ReSharper C++. ReSharper 2016.3.2 includes minor fixes in code analysis and highlighting, automatic code completion in TypeScript, and generation of Dispose pattern implementations. It speeds up the Inline Parameter refactoring and corrects parameter positions in the Change Signature refactoring. Find Usages receives an action to stop the current search. We've also fixed unfortunate bugs from the previous bugfix related to ReSharper Build

If you use dotTrace, you probably know it consists of two independent applications for performance analysis: Performance Viewer and Timeline Viewer. One of the greatest features that made Performance Viewer so helpful for quick performance evaluation was Subsystems. In dotTrace 2016.3, Subsystems have finally made it into dotTrace Timeline Viewer. What are subsystems? The mechanics of Subsystems are quite simple. In most cases, each subsystem just groups calls made within a certain namespace or assembly: WPF, LINQ, collections, strings, and so on. There are also certain special subsystems

Today we'd like to recap the most important changes in navigation and search that were introduced in ReSharper 2016.3. Find Results window is populated asynchronously If your solution is large enough, finding references of heavily used symbols can take time, delaying work with your code. To address this issue, we updated the usage search mechanism to make it async. Both Usages of Symbol pop-up and Find Results window are filled asynchronously, allowing you to work with partial search results. If you invoke Usages of Symbol (Shift + Alt + F12) and notice that search is taking a long time,

dotTrace 2016.3 introduces a new Events window which is available in both standalone dotTrace and dotTrace integrated in Visual Studio. To open the window in the standalone Timeline Viewer, use the View | Events menu: In Visual Studio, click Show Events in the Performance Profiler window: (more…)

After we released the initial continuous testing support in dotCover, the most popular response was "Cool, but this could be a lot more useful if highlighting was able to indicate test results." Indeed, before 2016.3, dotCover's highlighting was used only to indicate code coverage: dotCover 2016.3 finally addresses the issue. First, we got rid of colored backgrounds. Now, we use a small colored marker in the left gutter. Second and most important, we've completely changed the highlighting logic. Now, it not only shows whether a statement is covered by tests but also indicates test resul

ReSharper Ultimate 2016.3 introduces a new infrastructure for language injections in string literals, which enables ReSharper to treat particular string literal contents as a piece of code written in one of the supported programming languages: C# or ECMAScript regular expressions language, CSS, HTML, JSON or JavaScript. You can inject a language into a string literal in one of the following ways. Method 1: "Mark as injected language" context action When you open the Alt+Enter menu on a string literal, you’ll see a "Mark as injected language" item. In the submenu, choose one of the sup

Looking for a bugfix release? We have one! ReSharper Ultimate 2016.3.1 is now available for download. This update addresses a selection of issues in ReSharper and ReSharper C++. ReSharper 2016.3.1 is mostly about integrating into Visual Studio 2017 RC. We've received a lot of complaints about 2016.3 not detecting a Visual Studio 2017 RC installation. In all cases, repairing the Visual Studio installation would fix the issue, and based on this experience, we've updated the installer to detect (and warn about) incomplete Visual Studio installations. Other than that, the new ReSharper fixes

Probably, there is no person in the world who knows ReSharper in all its diversity. Even proficient ReSharper users normally only use a limited set of their favorite ReSharper actions in their everyday life. Though this set can be wide enough, there's always a chance you miss some important ReSharper tricks that can make your development workflow easier. But where and how should you get to know and try them? We at JetBrains are continuously working on all possible ways of communication, such as blog posts, learning videos and online help. For example, if you want an easy way to try a featur

We have just finalized an update to ReSharper Ultimate, and we invite you to check out what's new and download ReSharper Ultimate 2016.3 RTM! Watch the following video for a summary of what is new in ReSharper Ultimate 2016.3, or read on for the main highlights of this release: ReSharper In addition to 700+ fixes, major highlights of ReSharper 2016.3 are the following: Visual Studio 2017 RC initial support. All ReSharper Ultimate tools now support Visual Studio 2017 RC, including the new .csproj based .NET Core projects. Please note that though Visual Studio 2017 is marked as "RC

The new release is now so close, you can almost taste it: please download ReSharper Ultimate 2016.3 Release Candidate. If you have watched the progress of Early Access Program but were hesitant to try the early builds in your production environment, Release Candidate is just the right build to test-drive 2016.3 in your daily work. Please do download the RC and let us know if there are any critical issues compared to the latest released version, 2016.2.2. Here's a quick recap of changes introduced in 2016.3: All ReSharper Ultimate tools can now work with Visual Studio 2017 RC (stil

We're nearing the end of the EAP cycle for ReSharper 2016.3. We've just released EAP 11, mostly focused on fixing bugs and stabilisation, and with only a couple of new features. Now is the time to try out ReSharper 2016.3, and let us know any issues you encounter. ReSharper C++ While EAP 9 introduced support for Visual Studio 2017 RC, changes to the project model meant that C++ projects didn't work. We're pleased to say that EAP 11 addresses this, and C++ projects are working again. However, we currently require the Enable faster project load property to be turned OFF.

With all the excitement of releasing the first public EAP build of Rider last week, we didn't post about ReSharper Ultimate 2016.3 EAP 9. And now we've released EAP 10, so let's get caught up! Visual Studio 2017 RC ReSharper Ultimate products now have initial support for Visual Studio 2017 RC, including the new .csproj based .NET Core projects. It's important to note, however, that even though VS2017 is marked as "RC", there are a number of features and architectural changes that are currently marked as "preview". As such, we are still working on support for some of these new Visual Studio

Microsoft has just announced its latest IDE preview release, and we're here to sim-ship a compatible version of ReSharper Ultimate. Just get ReSharper Ultimate 2016.3 EAP 9 and install it into Visual Studio 2017 RC. You should be able to install all tools that are included in ReSharper Ultimate, namely ReSharper, ReSharper C++, dotCover, dotTrace and dotMemory. Granted, both the new Visual Studio and the ReSharper EAP are pre-release products, so issues are to be expected here and there. Please try installing the EAP build in Visual Studio 2017 RC and let us know how it works for you.

ReSharper Ultimate 2016.3 EAP 8 is here. In this build, we fixed another bunch of issues and added a few new features. ReSharper External stack traces open automatically Stack Trace Explorer now lets you open external stack traces even faster - if you copy a stack trace that contains symbols from the currently opened solution and then switch focus to Visual Studio, ReSharper will automatically load it to the Stack Trace Explorer without the need of pressing any shortcuts. This behavior is configurable on the Tools | Stack Trace Explorer options page. Decompiling directly from nu

Another build of ReSharper Ultimate 2016.3 EAP is out. Build number 7 fixes dozens of issues and brings a set of new and improved features. ReSharper New code generation actions for C# and VB.NET The Generate menu (Alt+Insert in a class) gets 3 new actions: Relational members helps you automatically overload relational opeartors (>, . New options for C++ formatter: 'Spaces wihin parentheses in cast expressions' and 'Place enumerators on new line'. dotTrace In addition to multiple performance improvements, dotTrace also delivers a number of new features in this build
