Adding custom helper tags

I am trying to add a special tag helper, but when I try to add an assembly as a link in _ViewImports.cshtml, it does not recognize it.

I do this (_ViewImports.cshtml):

@using ProjectName.Web.Main
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
@addTagHelper *, TagHelpers

and also I tried:

@addTagHelper *, ProjectName.Web.Main.TagHelpers

my tag helper looks like this:

using Microsoft.AspNetCore.Razor.TagHelpers;
namespace ProjectName.Web.Main.TagHelpers
{
    [HtmlTargetElement(Attributes="class")]
    public class CssClassTagHelper : TagHelper
    {
        public override void Process(TagHelperContext context, TagHelperOutput output)
        {
            output.Attributes.Add(new TagHelperAttribute("class","testing"));

        }
    }
}

but when I run the application, I get the following exception:

Cannot resolve TagHelper containing assembly "TagHelpers". Error: Failed to load the file or assembly 'TagHelpers, Culture = neutral, PublicKeyToken = null' or one of its dependencies. The system cannot find the specified file. @AddTagHelper *, TagHelpers

I already have googled, but I get mixed answers between different versions of dotnetcore until I find no solution.

I am using RC2.

any ideas, suggestions?
