checking. To build this using .NET core, run (in this directory):
dotnet restore
dotnet build project.json
dotnet build core.csproj -c Release
If you are building with the cmake system, you should first
copy over files that are produced by the compiler into
this directory. You need to copy over Native.cs and Enumeration.cs
-- good luck!
