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:
OpenCvSharp5.WindowsorOpenCvSharp5.Windows.Slim- Linux:
OpenCvSharp5+OpenCvSharp5.official.runtime.linux-x64
The
OpenCvSharp5.*runtime packages target OpenCV 5.x. An identically-namedOpenCvSharp4.*counterpart (OpenCV 4.13.0) is also published for .NET Framework / older runtimes.
🔄 Already using OpenCvSharp4? See the Migration Guide (4 → 5) on GitHub for target framework changes, package/namespace renames, and OpenCV 5 API changes.
The Linux linux-x64 packages are built on manylinux_2_28 (glibc 2.28) and work on Ubuntu 20.04+, Debian 10+, RHEL/AlmaLinux 8+, and other Linux distributions. The full (non-slim) package includes FFmpeg (LGPL v2.1) and Tesseract statically linked.
Linux
highguidependency: The fulllinux-x64package uses GTK3 forhighgui(Cv2.ImShow,Cv2.WaitKey, etc.). GTK3 is pre-installed on standard Ubuntu/Debian/RHEL environments. In minimal or container environments where it is absent, install it manually:
- Ubuntu/Debian:
apt-get install libgtk-3-0- RHEL/AlmaLinux:
dnf install gtk3For headless servers or minimal containers, use the slim package (
OpenCvSharp5.official.runtime.linux-x64.slim) instead, which disableshighguiand has no GUI dependencies.
macOS: The
osx.x64andosx.arm64packages include FFmpeg, Tesseract, Freetype, and all standard OpenCV modules, statically linked.

Note:
OpenCvSharp5.runtime.linux-armhas been renamed toOpenCvSharp5.runtime.linux-arm64to correctly reflect the ARM64 (AArch64) RID. The old package is kept as a compatibility shim that automatically pulls in the renamed package, but new projects should referenceOpenCvSharp5.runtime.linux-arm64directly.
Slim Profile
The slim packages bundle a smaller native library with a reduced OpenCV module set:
| Modules | |
|---|---|
| Enabled | core, imgproc, imgcodecs, calib3d, features2d, flann, objdetect, photo |
| Disabled | contrib, dnn, ml, video, videoio, highgui, stitching, barcode |
