System.ValueTuple won't install properly

Question

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.

Hi,did you restore your package on TeamCity?Please refer to [this](https://blog.jetbrains.com/teamcity/2013/08/nuget-package-restore-with-teamcity/). — Mr Qian, Dec 11 '19 at 09:33
Besides, when you install the nuget `System.ValueTuple 4.5.0` in the local Visual Studio, please try to [clean nuget caches](https://learn.microsoft.com/en-us/nuget/consume-packages/managing-the-global-packages-and-cache-folders#clearing-local-folders) and then install the package. In addition, please share the `packages.config`(if you used) and `xxx.csproj` which will be helpful. — Mr Qian, Dec 11 '19 at 09:38
TeamCity Nuget Restore is step 3. Cleaning and reinstalling didn't seem to affect it. — Jonathan Kuhl, Dec 11 '19 at 15:58
Does this answer your question? ['System.ValueTuple, Version=0.0.0.0 required for Add-Migration on .NET 4.6.1 Class Library](https://stackoverflow.com/questions/45978173/system-valuetuple-version-0-0-0-0-required-for-add-migration-on-net-4-6-1-cla) — Paddy, Dec 11 '19 at 16:11
l think you could try to use [BindRedirect](https://learn.microsoft.com/en-us/dotnet/framework/configure-apps/file-schema/runtime/bindingredirect-element) to include the old version of `System.ValueTuple` in `web.config`. — Mr Qian, Dec 13 '19 at 10:27
