System.ValueTuple won't install properly

I'm having trouble deploying a .NET application that works perfectly fine on localhost. The application is passed through TeamCity and then Octodeploy to be hosted on a server. When I navigate to a page that performs a query on the database, and submit that query, I get the following exception:

Could not load file or assembly 'System.ValueTuple, Version=0.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies.
The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

This occurs when Microsoft.EntityFrameworkCore tries to construct DbContext.

In Visual Studio, I have installed System.ValueTuple 4.5.0 through Nuget, but it shows in my references with a warning symbol and if I inspect properties, it's shows version 0.0.0.0. However the dll is in my packages folder inside a net461 folder. Furthermore it's also in my packages folder on Github so TeamCity/Octodeploy should also have access to it.

This is VS2017, and Net Framework 4.6.1. I do not have the option to upgrade to 4.7, where ValueTuple is included as default, and downgrading to 4.6 caused more problems.

How can I make the little warning disappear and the reference actually behave? Is there a way I can point to it's location in packages? Adding it as a reference doesn't seem to help. Adding automatic redirects to csproj doesn't seem to help. Uninstalling it doesn't help either, even though it works locally without it installed.
