Tag Helpers Not Executing

I just moved some views into a new Core project and was converting my HtmlHelper tags to TagHelpers. They bind correctly but they are not doming any "work". E.g., they label asp-for doesn't pick up the DisplayName attributes and the validators don't fire. I'm guessing it has to do with a JavaScript thing sine the old page included some JavaScript using a @Script. I'm not sure where to start tarcking this down.
