Description

    public async Task<int> InsertAsync (App app)
    {
        await db.ExecuteAsync ("insert into app (name, icon_url, home_page_url)" +
            "values (?, ?, ?)", app.name, app.iconUrl, app.homePageUrl);
        int id = await db.ExecuteScalarAsync<int> ("select last_insert_rowid();"); 
        return id; // Returns the id of the the object being inserted.
    }

id will always return 0. Using the nonasync version returns the correct id number.
