Yes, .NET Core is supported as a server and client platform by both Remoting SDK and Data Abstract.
Even more, .NET Standard is supported as server and client platform as well (the only limitation there is that Data Abstract Scripting is not supported on .NET Standard).
I’ve attached ta sample project: ROSDKServer.zip (2.6 KB)
They are under development right now. Shoul be available in the next build(s).
Check the sample project. There is a file named
licenses.licx. During build time this file is used by .NET build system to check licenses and compile licenses. Seems your project was missing that file.
