ReSharper Ultimate 10.1 EAP 2

The first EAP build of ReSharper Ultimate 10.1 introduced a massive list of new features and improvements, which spanned two blog posts. And here we are today with another EAP build, which you can give a try right away.


The most notable changes in ReSharper were merged this time by the JavaScript/TypeScript team. Among these changes are improvements in performance of caches and File Structure view, reworked Rename refactoring (which can now rename files corresponding to TypeScript types), as well as support for TypeScript implementations and overrides in Find Usages.

TypeScript keywords var, let, and const are now resolved according to the types they reference. This means that you can Ctrl-click these keywords to go the corresponding type declarations or just hover the mouse over to learn what a keyword refers to.

JavaScript/TypeScript formatter settings became much more granular. You can now specify the right margin for your code and define whether and how various code constructs should be wrapped. For example, you can specify where to place dots in multi-line chained method calls or you can opt for a ‘comma-first’ style for lists, object literals and function calls.

ReSharper 10.1 also brings initial support for Node.js. All ReSharper goodies you are well familiar with, like completion, code inspections, quick-fixes, and navigation features are now available for Node.js. However, we badly need your feedback on how ReSharper handles different things in your specific scenarios with Node.js.

For a long time, opening .nupkg files from disk was the only way to load assemblies from NuGet packages. In this dotPeek EAP build, you can try two more ways: find and load NuGet packages (and their dependencies if necessary) from any online package source, or load packages listed in a packages.config file in your Visual Studio project.

Another handy improvement is that dotPeek automatically highlights usages of the symbol under the caret. We hope now that obfuscated identifiers will not get lost as easily in decompiled code.

All your navigation history through dotMemory profiling results is now recorded and you can quickly return to any view or diagram that you once opened using the browser-style Back and Forward buttons.

Coverage filters, which let you ignore specific parts of your code when calculating coverage, are now supported in Continuous Testing.

    What about VB14 new language feature set support ( Why this major issue hasn’t been addressed yet? And more importantly, when, if ever, do you plan to fix it?

    All of these new features are great (loving the node.js support finally!), but what’d be even better is if you could fix the bug that’s been around for 2 or 3 major versions now where when I’m typing a random file opens at a random position and I start typing in that instead of the original file I was working on. This bug, along with the general increase in slowness of R#, is one of the leading reasons I didn’t want to renew my subscription for R# 10 (which also has the bug still).

      Thanks for your feedback, Brian.
      The bug with opening a random file you’re describing would receive our highest attention if we could reproduce it. According to our issue tracker, noone has reported anything similar so far. If you have a repro case, or at least what was the language and project type please send it to us asap. We would be also very thankful if you could tell us what exactly is wrong with renewing your subscription.

        +1. It happens to me quite often, working on C# projects. I still haven’t determined what exactly triggers it, but it seems (because I am a fast typer) that I may be triggering by accident some kind of “open last closed file” or “go to the last position of another file” shortcut. It’s very annoying but I never opened an issue in the tracker as I don’t know how to reproduce it.

      We haven’t mention it in these blog posts, but the completing characters setting for C++ is alredy there in this EAP build. Please download it and check it out.

      Hi Martin,
      Unfortunately, there are no definite plans to fix it in the 10.1 release. But please do vote for it in the issue tracker to raise it in the priority list.

    Appreciating the dedication you put into your blog and detailed information you provide.
    It’s good to come across a blog every once in a while that isn’t the same outdated
    rehashed material. Great read! I’ve saved your site and I’m including your
    RSS feeds to my Google account.

    Hi, I have just installed 10.1 update I am using it on a project with typescript.
    Does ReSharper typescript support the tsconfig.json file ?

    I have it setup to pickup all types with the “exclude” feature.

    “exclude”: [

    Which works fine for Visual Studio 2015 native, and in atom with atom-typescript extensions.

    As it appears ReSharper can’t find any of the type definitions.

      Thanks a lot for reporting the issue, I suppose it is the same issue as

      This change was never reflected in the specification (which is always obsolete, anyways), and they never announced it. The only documentation I have now found about this is in the tutorials, he-he.

      Sorry for any inconvenience, and thanks for understanding. Will fix this for the bugfix update for 2016.1.
