ReSharper Ultimate 2016.3 EAP. What’s new in builds 2 and 3

We’re up to build number 3 in the ReSharper Ultimate 2016.3 EAP. Let’s take a look at what’s changed in the last couple of builds.

Visual Studio 15 and new language versions

Firstly, EAP3 adds support for VS “15” Preview 5. As ever with a preview Visual Studio release, there may be issues with integration (we’re aware of potential issues with MSTest discovery), and we’re still working on adding support for some of the new functionality, so please let us know if you encounter anything that isn’t working right.

We’re also hard at work on C# 7.0 and VB.NET 15 support. The latest builds understand VB.NET binary literals and digit separators, and introduces basic support for C# 7.0 out variables.

C# also gets a nice new typing assist: when you type  $ to start an interpolated string literal, ReSharper will automatically complete the  $"" and insert the text caret between the quotes.

Finally for C#, another small addition that demonstrates a very powerful feature of ReSharper’s Structural Search and Replace – the “match similar constructs” feature now matches integer constants, regardless of how they’re encoded.

JavaScript and TypeScript

JavaScript and TypeScript get a new options page that improves how ReSharper works with third party library code and generated code. From this page, you can mark a JavaScript, TypeScript or JSON file, by name, file mask or even an entire folder as either “skipped” or “library”.

Skipped code is completely ignored by ReSharper – we will not index the file at all. This is useful when you have a file in your project that ReSharper would normally recognise as JavaScript, TypeScript or JSON – perhaps a generated, minified file, or a script that is already gzipped, but you don’t want the contents to appear in code completion or navigation.

Library code is treated as non-user code by ReSharper. The contents are still indexed, and appear in code completion and navigation, but inspections are not run. Useful for including third party code, e.g. jquery.js, where you don’t maintain the code yourself, and ReSharper’s inspections are not relevant to you.

ReSharper C++

ReSharper C++ has had some updates, too, starting with more memory optimisations, as well as adding support for the Catch C++ unit test framework. We now also support analysing C++ as part of the ReSharper Command Line Tools, meaning you can generate an XML report as part of a CI build.

.NET Core

EAP 1 introduced support for running .NET Core unit tests for NUnit and xUnit.net, and with the new EAPs, you can now debug .NET Core tests, as well.

And speaking of xUnit.net, we’ve fixed a performance issue that could freeze the UI if you had a “theory” test that generated a very large number of test rows at runtime.

As ever, please download and give it a go. And if you encounter any issues, please let us know!

    Please change the ugly Build & Run window and do something both visually appealing and actually useful such as the free Buildvision extension. I’m tired and annoyed with having to remember the difference between dark grey, light grey, blue, purple, green, yellow, etc… It’s ridiculous. Yes, I know that I can hover over each project and see what the cryptic color actually means, but in a solution with 27 projects it’s really annoying and the rainbow colors become more than useless as they are a hindrance now.

    I would like to see VB.Net razor views come up to parity with C# razor views. I’m at a company that is all VB.Net, and I really miss some of the C# only features when working on MVC projects.

  5. I would also love to see that new Third-Party Code feature for CSS. Resharper has a tendency to complain about issues in Bootstrap and other CSS libraries and I would love to have an elegant way to silence those warnings.

      Sounds like a good idea! I’ve added a new issue (RSRP-461293) that you can comment on, track and vote for. In the meantime, you should be able to add the third party items into the “Generated Code” options page, which should have a similar effect.

    • Anton Lobov says:

      Thanks, Etienne and Matt. I remade this options page, and now it’s applicable to all Web languages (JS/TS/CSS/HTML/JSON). Comes in the EAP 5.

    Will .NET Core dotCover support be included in final 2016.3?

    • Matt Ellis says:

      While we are working on .NET Core/CoreCLR functionality, we’re not ready to commit to features or schedules just yet.

  7. Mike-EEE says:

    +1 to Chris Owens’ comment. It would be nice to see the packages organized more logically as well, where the bottom represents the most common (“lower-level”) and the top represents implementation (“higher-level”) applications, etc.

      Durp… the Reply button wasn’t showing up. Since you don’t provide a way to edit your posts or feature a more modern-day forum solution/experience such as Disqus, admin. 😉 Please feel free to delete this comment and place the original under Chris’ comment. Thank you!
