Assembly missing in Razor

[jchannon]

In index.cshtml if you have

@if(postPaged.Series.Parts.Any()) {
    <text>HIIIII</text>
   }

This throws an exception. The response body in ThrowIfUnsuccessful shows that it wants a reference to System for SortedList. I added this via a Razor section in the config file but it still errors. I tried adding using statements to the view, casting the model in the view but still threw the error.

Over to you blessed touretted on
