When I build my solution its response is 1 error. But it is empty in the error list so can't see what the error is
<p>How is this possible? In the build response there is one error but when I look at the error list nothing there. </p>

<p>Could it be that I need to download some packages for that function? Cause I am using the new ASP.NET Core 1.0. But when I take away a ";" sign somewhere the error list suddenly works. So it does work but what could the problem be ?</p>
