FastNote

FastNote is a Visual Studio WPF project that mimics the Windows 11 Notepad shell while keeping large-file opening fast through streaming and background indexing.

What it does

• Windows 11 Notepad-inspired light and dark themes
• Native-style menu bar, single-tab shell, plain editor canvas, and status bar
• Progressive open path: the first chunk appears immediately, then the rest of the file indexes in the background
• Word wrap and zoom controls

Projects

• FastNote.App: WPF desktop UI
• FastNote.Core: streaming file reader and line indexer
• FastNote.Bench: benchmark harness for initial-open versus full-index timing

Build

dotnet build FastNote.slnx -c Release

Benchmark

dotnet run --project FastNote.Bench\FastNote.Bench.csproj -c Release -- <path-to-file>
