We’re excited to announce the release of GroupDocs.Viewer for .NET UI 8.1.1 – the latest update to our open‑source ASP.NET Core document viewer built for GroupDocs.Viewer for .NET.

This release introduces performance improvements with Angular 19, enhanced documentation via NuGet READMEs, and key bug fixes that make the viewer more stable and reliable. The update is now available on NuGet and GitHub.

🚀 Qué hay de nuevo en 8.1.1

1️⃣ UI de Angular actualizada

The Aplicación cliente has been upgraded from Angular 16 to Angular 19, resulting in faster loading and rendering. This ensures a consistent experience across the UI and the Visor en línea gratuito.

2️⃣ Recarga en caliente desactivada en los ejemplos

Sample applications often use local folders for caching. Previously, hot reload could mistakenly detect cache updates and refresh the app unexpectedly. To fix this, hot reload has been disabled in the launch settings of sample projects.

3️⃣ READMEs de paquetes NuGet

Each NuGet package now includes a README file that appears directly on its NuGet.org page, making it easier to understand usage without leaving the site.

Examples:

4️⃣ GroupDocs.Viewer actualizado
