OpenCvSharp Native Runtime Package

This is an internal implementation package for OpenCvSharp. It provides the native OpenCV shared library (OpenCvSharpExtern) for a specific platform.

In most cases you do not need to reference this package directly. Use one of the all-in-one packages instead:

• Windows: OpenCvSharp4.Windows or OpenCvSharp4.Windows.Slim
• Linux: OpenCvSharp4 + OpenCvSharp4.official.runtime.linux-x64

Available Runtime Packages

Package	Platform
OpenCvSharp4.runtime.win	Windows x64
OpenCvSharp4.runtime.win.slim	Windows x64 (slim)
OpenCvSharp4.official.runtime.linux-x64	Linux x64 (portable RID)
OpenCvSharp4.official.runtime.linux-x64.slim	Linux x64 (portable RID, slim)
OpenCvSharp4.official.runtime.ubuntu.22.04-x64	Ubuntu 22.04 x64
OpenCvSharp4.official.runtime.ubuntu.22.04-x64.slim	Ubuntu 22.04 x64 (slim)
OpenCvSharp4.official.runtime.ubuntu.24.04-x64	Ubuntu 24.04 x64
OpenCvSharp4.official.runtime.ubuntu.24.04-x64.slim	Ubuntu 24.04 x64 (slim)
OpenCvSharp4.runtime.linux-arm	Linux ARM
OpenCvSharp4.runtime.osx.10.15-x64	macOS 10.15+ x64

Note: For Linux, the portable linux-x64 packages are recommended over the distro-specific ones. Distro-specific RIDs are no longer resolved automatically by .NET 8+.

	Modules
Enabled	core, imgproc, imgcodecs, calib3d, features2d, flann, objdetect, photo
