機能

• What's New:
  • The WPF suite is fully compatible with .NET 10. All associated DLLs, installers, NuGet packages, and Visual Studio Extensions have been updated to officially support this version, ensuring smooth integration with the latest .NET platforms.
  • The PdfViewer now includes AI Summarization support, enabling users to generate summaries of documents. This feature helps users quickly grasp key points and main ideas without having to read the entire text. The feature can be configured using one of the following services: AzureOpenAI, OpenAI, or Ollama.
• Common:
  • The product is now fully compatible with Visual Studio 2026. This includes both the installers and extensions, ensuring a smooth integration and development experience in the latest IDE version.
  • Updated System.Drawing.Common version to 8.0.0 and removed UseWindowsForms dependency for .NET 8/9. As a result, a FileNotFoundException no longer occurs during the resolution of the System.Windows.Forms assembly within the InitializeProperties method after publishing a .NET 9 application.
• Dependencies:
  • Updated Telerik Document Processing Library (DPL) version to 2025.4.1104.

  • Introduced an option to include additional content in the drop-down area, as well as the ability to position it.
• DataServiceDataSource:
  • Discontinued Telerik.Windows.Controls.DataServices50 and Telerik.Windows.Controls.DataServices60 assemblies. The Telerik.Windows.Controls.DataServices assembly now relies on Microsoft.OData.Client version 7.8.3.
• EntityFrameworkDataSource:
  • Discontinued Telerik.Windows.Controls.EntityFramework assembly. For existing projects on .NET Framework 4.6.2, the Telerik.Windows.Controls.EntityFramework60 assembly remains available and has been updated to use Entity Framework 6.5.1 for improved stability and compatibility.

  • Fixed issue where ArgumentOutOfRangeException is raised when the culture is set to th-TH (Thailand) and the ItemsSource is rebound to a non-initialized collection.

• PDF Viewer:
  • The PdfViewer now includes AI Summarization support, enabling users to generate summaries of documents. This feature helps users quickly grasp key points and main ideas without having to read the entire text. The feature can be configured using one of the following services: AzureOpenAI, OpenAI, or Ollama.
