I have 2 projects: X.SQL which uses SQLite, and Y - a console app, which uses X.SQL. When I build Y, interop files are copied to and folders, as expected. If I build again, interop files are removed, which should not happen.
Please notice that they are not removed from

Steps to reproduce:
1. Create project X.SQL, install System.data.SQLite from Nuget
2. Create Y, add reference X.SQL
3. Build/Rebuild
4. Build/Run. interop files vanishes from Y
Any solution?
