Haha, this is becoming a thing.. we both ping each other on different platforms and only see it days later 😁 I already merged and deployed. Thanks for the PR!

JetBrains Rider has a very clever way to handle cases were there are multiple function calls on the same line when debugging, you use the arrows to select which one you want to step into. It's the first time I see this and now I wish all debuggers supported it.

Very pleased how the IDE Browser 🌐 plugin turned out. Great for more authentic docs previews, debugging of web apps, and generally fewer context switches. Version 1.1.0 currently awaits approval 🚨 plugins.jetbrains.com/plugin/29952...

A neat little browser as a tool window in @rider.jetbrains.com. The plugin also ships with run configuration hooks to allow opening a URL upon project start. 🌐🐣 plugins.jetbrains.com/plugin/29952...

It feels so much nicer to use Rider for debugging now. I was OK'ish with its speeds before, now I actully started to like it :) And with RAM prices these days, man its nice to starting saving some on debugging.

Before C# 14, there were just a few rare erasure conflicts in C#, like when u define overloads differing only by `ref` /`out`. With C# 14 extensions, we are one step closer to Java, with its stupid "have the same erasure" conflicts

'Huge architectural change' to JetBrains ReSharper cuts Visual Studio freezes
Six years in the making, but some features do not work yet, and has the tool been overtaken by AI? JetBrains has updated ReSharper, its .NET plugin for Visual Studio, with an out-of-process design that achieves a 61 percent reduction in UI freezes, the company claims. However, the new mode has reduced functionality.…

Naming stuff is hard for me. Patterns missed, can't see the forest for the trees, or simply "language skillz". #Junie in #Rider has been a gamechanger, because it automatically gathers the context, weighs pros and cons, and doesn't get tired of me being picky about options.

I want as many developers as possible to experience the joy of refactoring their code when they have a good test suite by their side. It's infectious. You'd want that feeling all the time.

I'm genuinly in love with this action. Whenever I write tests that could potentially affect each other, I'll put them under stress. It also works with multi-select, so you can easily isolate the troublesome combinations.

If it's the same code that was just working, and you've checked timestamps, then logs would indeed be helpful. I assume the lazy code was actually executed.
