Multiple Visual Studio Projects in Unity

Question

I am trying to move all of my non Unity-specific code into classes which don't inherit from MonoBehaviour, similar to this. I created a separate Visual Studio project called Models for all of my non-MonoBehaviour classes, and I added that project to the Visual Studio solution. However, I can't add a reference to my Models project to my Unity project through Visual Studio (the Add Reference button isn't there when I click on the Unity project, and I've read that Unity automatically rebuilds its Visual Studio project anyway, so any added references would be lost), so I set the output location of my Models .dll to the Assets folder in Unity and I added that .dll to my Project view in Unity. That's all working. The problem is that whenever I rebuild my Models project, the Unity project in Visual Studio doesn't seem to pick up the changes, so I have to delete the .dll from the Project view in Unity and re-add it every time I make any changes to the Models project.

Is there a way to have Visual Studio automatically see the changes to my Models .dll, or is there a better way to go about having my Unity project reference another Visual Studio project?

I tried researching this for you, and the closest thing i could find so far is this: http://devleader.ca/2015/02/08/multiple-c-projects-unity-3d-solution/

It details how to adopt unity and visual studio to work well and sync up correctly without rebuilding/running/other crazy things to get the projects working together.

Hope it helps.
