.NET MAUI PDF Viewer
Maintain zoom level in single page view mode
A new capability has been introduced that allows the PDF Viewer to retain the current zoom level when navigating between pages in single page view mode.
When enabled, the viewer preserves the user-defined zoom level instead of resetting it on each page transition. This ensures a consistent viewing experience, particularly when working with documents that contain detailed graphics, small text, or zoom-critical content.

After enabling zoom persistence:
Access custom stamp annotation views
Users can retrieve visual elements associated with custom stamp annotations. Accessing these elements provides greater flexibility in customizing and managing stamp behavior after they are added to a page, making it particularly valuable when integrating stamps into advanced review or approval workflows.
Developers can now retrieve, modify, or dynamically update the appearance and behavior of custom stamps once they are placed in the document, enabling more interactive and adaptable annotation scenarios.
Visual Studio Code Extension
Syncfusion PDF Viewer SDK Extension - Visual Studio Code
The PDF Viewer SDK Extension for Visual Studio Code allows developers to integrate Syncfusion PDF Viewer components into Blazor and .NET MAUI apps. It provides dedicated project templates for both platforms, plus convenient code snippets: Blazor snippets insert component code straight into Razor files, while MAUI snippets add it directly to XAML files.
