Manage Document Metadata using .NET API
Important Note: Starting from 24.4.0, the GroupDocs.Metadata package has been split into two distinct platform packages: .NET Standard and .NET Framework. The GroupDocs.Metadata package is specifically designed to support the .NET Standard platform, making it compatible with .NET Core, .NET 5, .NET 6, etc. It includes backward compatibility improvements, allowing it to function with .NET Framework versions starting from 4.7.2. In addition, we have introduced the GroupDocs.Metadata.NETFramework package, which is optimized to run seamlessly in the .NET Framework runtime because it includes all the GroupDocs product libraries in their respective .NET Framework versions. It is tailored specifically for .NET Framework users and offers better dependency resolution for those utilizing the .NET Framework. We hope these changes will enhance your experience and provide a more streamlined approach to using the GroupDocs.Metadata package. If you have any further questions or concerns, please don't hesitate to reach out to our free support forum.
