This is the first release of the OASIS Runtime. The version is v2.3.1 so it stays in sync with the current LIVE OASIS API HTTP REST Service (also uses the same OASIS Runtime), which is currently at v2.3.1:
https://api.oasisplatform.world.
This runtime is designed to be used in OAPP's (OASIS Applications) that can work both online and offline and because they are using the OASIS API directly through the native integrated DLL's they are also faster than making calling to the HTTP REST Service.
The NextGenSoftware.OASIS.API.Native.Integrated.EndPoint NuGet package wraps around the OASIS Runtime providing an entry-point into the API. The OASIS Runtime is not designed to be used directly on its own but you can be if you wish. It is recommended you use either the OASIS API REST Service or the NextGenSoftware.OASIS.API.Native.Integrated.EndPoint NuGet package.
