ServerException When Attempting to call ClientContext.ExecuteQuery

When I tried to deploy/debug my auto hosted app this morning I receive the following exception on the first ClientContext.ExecuteQuery call. The code is unchanged from when it last worked (about 18 hours ago), so I'm fairlyconfident it's not on my end.

Microsoft.SharePoint.Client.ServerException occurred
  HResult=-2146233088
