Oucx Reader

A focused PDF reader for Windows, built with C#, WPF, .NET 10, and the Microsoft Edge WebView2 PDF engine.

The application includes an original Oucx Reader icon embedded in the executable and displayed in the window and taskbar.

Features

• Open PDFs from the file picker or by drag-and-drop
• Recently opened document list
• Page navigation and zoom controls
• Search and print through the native Edge PDF toolbar/shortcuts
• Full-screen reading mode
• Dark, distraction-free interface

Run

dotnet restore
dotnet run --project Oucx.Reader.csproj

Releases and updates

Push a semantic-version tag such as v1.0.0 to build a self-contained Windows x64 package and publish it as a GitHub Release:

git tag v1.0.0
git push origin v1.0.0

Each release includes a self-contained Oucx.Reader.exe for direct download, its SHA-256 checksum, and a ZIP package used by automatic updates.

Packaged builds check the latest public GitHub Release at startup. When a newer stable version is available, the app offers to download it, verifies the release package's SHA-256 checksum, installs it after shutdown, and restarts automatically.

The WebView2 Runtime is included with current Windows 10 and Windows 11 installations. If the app reports that its PDF engine cannot start, install the Evergreen WebView2 Runtime from Microsoft.
