I have installed the VSProlog extension in my Visual Studio 2015, from here: https://visualstudiogallery.msdn.microsoft.com/50f0f293-bcb5-4f95-a9d0-afff92306973
Going to Tools>Extensions and updates I can see the extension installed, and it's enabled. Everything seems fine.
But trying to create a simple prolog .pl or .ari file, in File>New project... I can create C#, Visual Basic files, ASP, Python... but nothing appears related to Prolog.
How can I create a Prolog File in my Visual Studio?
