Continuous crashing on razor source

[spazmodius]

Issue Description

When I open detail.cshtml, and as I hover the mouse over various c# variables, I get no type information shown in the editor, but the Omnisharp log fills with ArgumentOutOfRangeException.

Further, analysis does not seem to find references to my types in cshtml files.
