Replacing Electron with .NET 10: Writing a zero-latency, SIMD-accelerated IDE (opens in new tab)

Modern development tools have normalized lag. As an industry, we’ve somehow accepted that opening a text editor should consume 2GB of RAM, and that typing rapidly should occasionally stutter while an extension parses a JSON tree on the UI thread. The standard playbook for building cross-platform editors today is to use Web Technologies (Electron/Tauri) or to drag along a decades-old monolithic C++ architecture. But when it comes to high-performance, memory-intensive data processing, C# and .N...
