inheritance problem when using dapper.contrib

[thdotnet]

Seems that if I have Foo model that inherits from Bar, when using Insert passing and instance of Foo, it's trying to insert into a Bar table.

public class Bar
{

}

public class Foo : Bar
{
   //properties
}

public class Repository
{
        public static void Insert<T>(string connectionString, T model) where T : Bar
        {
            using (var cnn = new SqlConnection(connectionString))
            {
                cnn.Open();
                cnn.Insert(model);
            }
        }
}
