A short blog today - this is more a reminder for future self than anything else.
If rendering a partial view and perhaps upgrading a site from .Net Framework to .Net Core. You might see this message output in to your rendered site -
System.Threading.Tasks.Task`1[Microsoft.AspNetCore.Html.IHtmlContent]
This is likely to be because you are replacing
@Html.Partial("yourPathToYourPartialView")
With
@Html.PartialAsync("yourPathToYourPartialView")
and you are almost correct, but you need to add await in from of the Html.
So you should have
@await Html.PartialAsync("yourPathToYourPartialView")
This removes the erronous output and displays your partial.
