Sqlite Primary Key doesn't work on Windows Phone 8.1

I'm creating a project for Windows Phone 8.1, using SQLite (sqlite-net). But to persist my entity, realize that the notes I'm putting in my properties (primary key, auto increment) are not being obeyed. The problem happens when I place my entities in a separate project to persistence project. If I make the whole process within the same project (persistence + entities) works perfectly. Does anyone know how can I solve this problem?
