For the past two weeks I’ve been working on reducing memory usage in #fsharp compiler service that we use in @JetBrainsRider
The latest measurements look really good! 🎉
And since the improvements are in FCS itself, other tools will get them too
- I've been working on #fsharp debug in @JetBrainsRider recently and, while we've managed to improve it a lot, it's become clear that many of the remaining issues are coming from the inlining done by F# compiler. Here's is a proposed fix:
- Smart Step Into is a game changer for debugging #fsharp code. And together with numerous stepping fixes it changes the debug experience completely
- This release brings a new powerful way to fix #fsharp type errors in your solution and adds improvements to existing features across the board 🎉 As always, here are the F# plugin release notes: github.com/JetBrains/resh…Rider 2025.3 has just landed! 🔥 Same-day compatibility with .NET 10, including full support for C# 14 features. 🏝️ Islands UI theme as the default now look ⏱️ Major startup and @UnrealEngine performance boosts ⭐ … And more exciting features! Dive into the latest updates
- A bunch of new #fsharp quick fixes are coming to @JetBrainsRider 2025.3 soon 🎉 They make it way easier to update types across your code — whether it’s refactoring a record field or changing an inferred parameter type
