//Licensed Mode
//db.UserName = "John Smith 101224";

//Set before OpenDatabase. Default storage is IsolatedStorageDatabase. Other options are:
//db.Storage = new MemoryDatabase(); //In memory database
//db.Storage = new FileDatabase();  
 
//Open the database
db.OpenDatabase();
 
//Add a single property index if it doesn't already exist
