ASP.NET Core 2.1 Razor Form, Post not reaching Controller

There was a lot of different help here, thanks especially to Kirk Larklin! There were three issues that was preventing my controller from picking up the data.

1. Browse.cshtml was missing the @addTagHelpers... I added the following:

   @addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
   @addTagHelper *, AuthoringTagHelpers
   

2. My CollectController.cs was missing a route... I added the following:

   [HttpPost, ValidateAntiForgeryToken]
   [Route("Index/Collect")] 
   

3. Finally, I renamed my controller post method from 'Collect' which conflicting with another method to Index and updated the asp-action in my Browse.CSHTML file to match.

   public IActionResult Index(Collect model)
   

Thanks for all the help!
