Most of my time programming #csharp I've been switching between two main IDEs: Microsoft Visual Studio (2026) and Jetbrains Rider. Rider is good for decompiling and debugging framework code, but very slow. My Core i9 13900H / 32GB RAM laptop wasn't powerful enough for Rider, I had to switch to desktop. Visual Studio is fast, but debugging framework code doesn't always work. So even in 2026, both are needed.
