ASP.NET 5 Conditional Anchor Tag Helper. This tag helper will omit the anchor tag if the href is null or empty.

readme.md

Example

🔥 Life Before TagHelper 🔥

@if (!String.IsNullOrWhiteSpace(Model.Url))
{
    <a href="@Model.Url"><img src="image.jpg" /></a>
}
else
{
    <img src="image.jpg" />
}

🍺 Life After TagHelper 🍺

<a asp-conditional href="@Model.Url"><img src="image.jpg" /></a>

ConditionalAnchorTagHelper.cs

namespace SecretOrange
{
    [HtmlTargetElement("a", Attributes = "asp-conditional")]
    public class ConditionalAnchorTagHelper : TagHelper
    {
        public override async void Process(TagHelperContext context, TagHelperOutput output)
        {
            var href = context.AllAttributes["href"]?.Value.ToString();

            if (String.IsNullOrWhiteSpace(href))
            {
                output.SuppressOutput();

                var childContent = await output.GetChildContentAsync();
                output.Content.SetHtmlContent(childContent);
            }
            else
            {
                output.Attributes.Remove(output.Attributes["asp-conditional"]);
            }
        }
    }
}

hmmm useful Tag helper to prevent if..else... in Razor.
