I am trying to install a NuGet Package from a private package source, and whenever I try to install or update a specific package, it doesn't appear in the project's references folder in Visual Studio.
The packages.config file says it is installed, but it isn't listed in the references. Has anyone else had this issue? Does anyone know how to fix it?
I am using Visual Studio 2015 Enterprise on a Windows 8.1 machine.

update-package -reinstallin the package manager console for that project
