title: Newtonsoft JSON package dependency means can't use SignalR with SDK Functions
body: <p>Microsoft.AspNetCore.SignalR 1.0.0-rc1-final has a dependency on Newtonsoft.Json (>= 11.0.2), but Microsoft.NET.Sdk.Functions 1.0.13 -> Newtonsoft.Json (= 10.0.3).</p>
  
  <p>Does anyone know what's in version 11.0.2 of Newtonsoft.Json that breaks SDK.Functions?</p>
