Antlr4 + VS2017 + .Net Core

[RobertWalterU3d]

Hello,

I try to create a DLL that contains a Lexer and Parser generated by Antlr4 and that will work with .NET Core.

For this, I followed the guide to setup VS 2017 to use Antlr4. I created a new .Net Core class library project and added Antlr 4.6.6 via NuGet package manager.
However, when building the project (i.e. generating the Lexer and Parser), I get a bunch of build errors since the Antlr4 namespace cannot be resolved in the generated files.

I found this old issue and when I add explicit PackageReferences to the Antrl runtime, the generated cs files can be compiled fine.

<PackageReference Include="Antlr4.Runtime" Version="4.6.6" />

Is it still the recommended way to manually add the PackageReference to the CSPROJ file, or is there a better way?

Also, in the mentioned issue, the CodeGenerator is also manually added as a PackageReference. At least I don't need it to rid myself of the build errors, but maybe I still need it later?

<PackageReference Include="Antlr4.CodeGenerator" Version="4.6.6" PrivateAssets="all" />

Any help is appreciated.
