Azure Functions 2.0 Not Loading Referenced Libraries

I've created a new Azure Function in VS 2017.

Ran it, debugged it.

Then referenced a library of shared code and modified the code to call into the library.

Re-ran the function, upon calling the function it dies loading one of the dependent DLLs.

This seems to be publishing as a precompiled function and the inner bin that is referenced in the function.json as the home for the "scriptFile" has the DLLs including the one that is failing to load.

[1/5/2018 4:04:18 AM] ScriptHost initialization failed [1/5/2018 4:04:18 AM] System.Private.CoreLib: Could not load file or assembly 'Microsoft.AspNetCore.Mvc.Abstractions, Version=2.0.1.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. Could not find or load a specific file. (Exception from HRESULT: 0x80131621). System.Private.CoreLib: Could not load file or assembly 'Microsoft.AspNetCore.Mvc.Abstractions, Version=2.0.1.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

Is there a trick to getting the function to load these DLLs?
