CpuMath DllNotFoundException When Using ML.NET With Windows Forms

[SLane35]

System Information (please complete the following information):

• Windows 10
• ML.NET Version: 1.6.0
• .NET Version: .NET Framework 4.6.1 (some projects target 4.5.2)

Describe the bug
I have a solution with 14 projects, including 1 that includes ML.NET. It targets x64 and I use PackageReference. When I run the app in the debugger, it runs perfectly. When I publish it though, I get the following error:

Application: CentralTestML.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

Please note that this is a ClickOnce app that is published to a server running Windows Server 2012 R2 Standard.

To Reproduce
Steps to reproduce the behavior:

1. Publish app
2. Click the icon to update to the newest version
3. The new app installs, but never runs due to the above error.

Expected behavior
I expected the app to run properly.

Thank you!
