steps to reproduce: Using VS2012 ultimate (I'm sure any version will also work) create a class library project and right click on references and manage nuget packages. Using the nuget package manager, attempt to install System.Data.Sqlite (latest version as of 10.21.2015).
I get the following error message:

Of course, if I installed just the 'core' package it works. I don't understand why I can't install the official 'full' package.
