Including Dependencies That Target .NET 4.x in Travis While Using Unity

Question

I am using the Unity Game Engine for a school project. I use: https://github.com/GlitchEnzo/NuGetForUnity to download Nuget Packages, as Visual Studio's NuGet Package Manager doesn't play well when Unity regenerates the .sln file.

One of the packages I use is https://github.com/System-IO-Abstractions/System.IO.Abstractions

Locally, this works fine, however, when just having this dll as part of my project causes the Travis build to fail. I am unsure of the exact cause but I suspect it has to do with the build not being able to target the corect framework, as Unity by default targets .NET 3.5.

Is there a way that I can debug my build to find the target version or manually set the target version to .NET 4.0?

Any help would be greatly appreciated.

You can switch the Scripting Runtime Version in Unity to .Net 4.6 in the project settings

Go to the PlayerSettings

and there under Other Settings switch Scripting Runtime Version to Experimental (.Net 4.6 Equivalent)
