2016.2 EAP 5 - Cannot resolve symbol 'Json' in .cshtml

Hi,

I'm developing an asp.net core 1.0.0 MVC application.
I get the following error when using JsonHelper in .cshtml:

Cannot resolve symbol 'Json'

Some code:

<script language="javascript">
var data = @Html.Raw(Json.Serialize(@Model.TimeBasedStatistics));
</script>

The application builds and runs fine!
