SQLite Table Creation on Windows Phone 8

I've been following some tutorials on creating a SQLite database on Windows Phone 8 and I'm wondering what's the best/recommended way of creating the tables?

The most popular ways I've seen on tutorials I've followed do it where the tables are created in the App.xml.cs constructor using a method called IfFileExists(string file) to check if the database exists, and if it doesn't, then create the tables;

private async Task<bool> CheckFileExists(string fileName) 
{ 
    try 
    { 
        var store = await Windows.Storage.ApplicationData.Current.LocalFolder.GetFileAsync(fileName); 
        return true; 
    } 
    catch 
    { 
        return false; 
    } 
} 

public App() 
  { 
      if (!CheckFileExists("ContactsManager.sqlite").Result) 
            { 
                using (var db = new SQLiteConnection(DB_PATH)) 
                { 
                    db.CreateTable<Contacts>(); 
                } 
            }  
  } 

Another (the way I'm currently doing) show the tables being created in the Application_Launching method in the App.xml.cs class by making a connection, then using that connection to create the tables, or by creating the tables in a method in a DBHelper class, and calling that method in a TRY-CATCH(FileNotFoundException). The latter didn't work for me and kept giving me an SQLiteException.

How I'm doing it at the minute looks like;

private void Application_Launching(object sender, LaunchingEventArgs e)
{
    // Creating tables.
    Connection = new SQLiteConnection(ConnectionString);
    Connection.CreateTable<Table1>();
    Connection.CreateTable<Table2>();
    Connection.CreateTable<Table3>();
    Connection.CreateTable<Table4>();
    Connection.CreateTable<Table5>();
    Connection.CreateTable<Table6>();
    Connection.CreateTable<Table7>();
    // With Connection and ConnectionString being class properties.
}

This is a relatively small app, so through research I thought using SQLiteConnection rather than SQLiteAsyncConnection is best suited. At the minute I'm worried that the way I'm creating my tables/database, the tables/database will overwrite themselves each time the app is opened.
