Apache.Ignite.Core.dll works on all platforms (
IGNITE-2662), but it is just a library to be referenced by user code.
We also provide Apache.Ignite.exe which is windows-only, .NET Core can not run exe files.
Find a way to provide cross-platform standalone executable to be run on .NET Core. That could be a prebuilt .NET Core dll or a project to be started with dotnet run.
