Installation OpenTK does not require installation. Simply decompress the archive to a folder of your choice. Usage To use OpenTK, you need to reference "OpenTK.dll". Refer to http://www.opentk.com/doc for specific instructions. Regardless of your development environment and operating system, ensure that you copy "OpenTK.dll.config" to the output directory. Without OpenTK.dll.config, your application will not function on Linux or MacOS.
