Rider EAP 24 includes performance fixes, F# Interactive

Jura Gorohovsky

We have a new Rider EAP build for you today. Highlights of this build include performance and memory consumption fixes, Unity support improvements, and F# Interactive, accompanied by a few dozens of bug fixes.

Performance fixes

Last week, we were put to shame due to a performance impact that Rider was incurring on RavenDB development:

Investigating the report revealed a set of problems, and although we’re unable to fix all of them right away, we did get rid of some:

  • We modified the caching workflow so that files that are not part of a solution aren’t processed multiple times.
  • We fixed a memory problem whereby the file structure model would be stored in memory even without opening the Structure view. This should help tone down memory consumption when opening large files in the editor.
  • We optimized handling of external file changes, such as those that occur when you switch to a different Git branch.
  • We made the Unity plugin behave, and it should no longer track file changes in projects that have nothing to do with Unity (on larger solutions, this alone is expected to cut loading times down by 5-10 seconds.)

The fixes should hopefully make development in Rider a smoother experience on larger solutions, especially those containing large volumes of JavaScript or TypeScript code.

The RavenDB case helped reveal more problems that will take more time to get addressed, which means we’ll be planning some architectural changes in ReSharper and Rider for further releases later this year.

F# Interactive

You can now use the F# Interactive tool window for F# scripting: both without ever leaving the console and by throwing selected lines or selections from the text editor. There’s a separate keyboard shortcut to send to F# Interactive, and the action is also available in Rider’s mainstream Alt+Enter menu:

Unity support changes

First off, there’s something that we had done for EAP 23 but didn’t have a chance to talk about. We have recently refactored two separate Rider plugins for Unity into one plugin that:

  1. Is bundled with Rider;
  2. Installs a Unity Editor extension once you open a Unity solution in Rider.

In other Unity news, when opening a Unity solution, you will be prompted to disable Rider’s auto-save feature to prevent frequent recompilation, and Rider will in fact make these configuration changes for you:

More improvements

  • In the application menu, we have merged File > Open with File > Recent Projects for a single list that works whether or not you have a history of opening the solution that you’re currently looking for.
    File | Open includes recent solutions
  • Web.config and app.config received improved support with validation and completion for tags and attributes, as well as automatic insertion of required config sections.
    Required items auto-inserted in web.config

Download and try

Please download the latest Rider EAP build and give it a try. Do submit any exceptions that you encounter: it’s essential for us to have a profile of current exceptions before we switch to production builds as we wrap up for the release.

    Hmm, cant write left side curly bracket on Mac, alt + shift + 8 opens up unit test explorer
    Instead. This is really sommething that I shouldn’t need to remap myself, this is basic functionality.

    Thanks for this release. I have been looking forward to it. I was having some performance problems in EAP 23 with fsx files but this seems to be resolved now in EAP 24. Rider is a great product so far and keeps getting better, thanks!

    […] Vor knapp zwei Wochen hat JetBrains EAP 23 seiner Cross-Plattform-IDE für .NET veröffentlicht. Gestern erschien EAP 24 von Rider und bringt unter anderem Fixes für die Performance und den Speicherverbauch. Zu den wichtigsten Fehlerbehebungen gehören allerdings die Probleme, die Rider im Rahmen von RavenDB-Development verursachte. Hier konnten zwar nicht alle, aber immerhin einige Bugs gefixt werden. Laut dem Rider-Team brachte der RavenDB-Fall noch weitere Probleme ans Licht, deren Bearbeitung aber mehr Zeit benötige. Man plane sogar einige architekturelle Änderungen für ReSharper- und Rider-Releases im weiteren Verlauf des Jahres. Darüber hinaus haben die Macher folgende Neuerungen zu vermelden: Das F# Interactive Tool-Window lässt sich ab sofort für F#-Scripting nutzen und zwei Rider-Plugins für Unity wurden in ein neues Plugin refactort, das ab sofort mit Rider gebundelt wird. Der aktuellste Rider-Build kann hier runtergeladen werden, alle Details zum EAP 23 gibt es im offiziellen Blogpost. […]

    I really appreciate the update to the Unity plug-in. It’s to the point where I have no issue using Rider for my personal projects, and I think it’s almost ready to replace VS as my C# IDE.
