Get HTML Content string from Taghelper

Question

How do I get the HTML rendered from a Taghelper? Say I created a Taghelperfor a customized Checkbox. What would be the code to store the html in a variable?

checkboxTagHelper.ProcessAsync(checkboxContext, checkboxOutput);

In addition, I noticed renderHtmlAttributes does not work in .Net Core. However works in regular Mvc 4.6.3. Is this perhaps the correct method, and whats the equivalent in .Net Core?

 return $"<{innerOutput.TagName} {renderHtmlAttributes(innerOutput)}>{innerOutput.Content.GetContent()}</{innerOutput.TagName}>";

Just researching, I believe the answer is this. Seems to be working on my end.

return output.Content.GetContent();
