Answer 1

I found edymtt's answer right about blaming TableAdapters / Datasets, but instead of modifying the every time re-generated TableAdapter codefile, I found an other solution: to manually call .Dispose on the TableAdapter's child elements. (In .NET 4.5, latest SQLite 1.0.86)

using (var db = new testDataSet())
{
    using (testDataSetTableAdapters.UsersTableAdapter t = new testDataSetTableAdapters.UsersTableAdapter())
    {
        t.Fill(db.Users);
        //One of the following two is enough
        t.Connection.Dispose(); //THIS OR
        t.Adapter.Dispose();    //THIS LINE MAKES THE DB FREE
    }
    Console.WriteLine((from x in db.Users select x.Username).Count());
}
