ANTLR templates do not appear in new project system

Might this have to do with this old issue #61?

It actually turned out that the templates were mostly fine. In my first attempt to reproduce the problem, I wasn't able to because I was using the new project system to target net45. However, when I changed to netstandard1.3, the templates disappeared.

As I often do when examining template issues, I went and found one of the template files which still appeared in .NET Standard projects and opened its definition:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\ItemTemplates\CSharp\Code\1033\Class\Class.vstemplate

Comparing this to the templates for ANTLR, it was immediately clear where the difference lied.

I downloaded the Tvl.VisualStudio.Tools.Antlr.vsix file from build 1.0.44 and installed it in Visual Studio Professional 2017 (15.2.0+26430.15) and the extension seems to be enabled, but I'm unable to find the templates even for non-Core projects, I don't even have the "ANTLR" category in the add file pop-up. Am I missing something?

@kappa7194 Try uninstalling the extension, restarting Visual Studio, and then installing it again from the VSIX.

Found the problem, my fault: I downloaded and installed Tvl.VisualStudio.Tools.Antlr.vsix instead of Tvl.VisualStudio.Language.Antlr3.vsix.
