Why am I getting FileNotFoundException in Windows phone 8 using C#?

I am trying to check my db file existence in try block and in catch I am creating it.

public async Task<bool> CheckDbAsync()
{
    bool dbExist = true;
    try
    {
        StorageFile sf = await ApplicationData.Current.LocalFolder.GetFileAsync(DB_NAME);
    }
    catch(FileNotFoundException)
    {
        Conn = new SQLiteAsyncConnection(Path.Combine(ApplicationData.Current.LocalFolder.Path,"baby.db") , true);
        dbExist = false;
    }

    return dbExist;
}

Issue is I am getting same handled exception. Code breaks on my try block. Any idea why?

I have fixed the issue by using 

System.IO.File.Exists(string.Format(@"{0}\{1}", ApplicationData.Current.LocalFolder.Path, DB_NAME));

which returns a bool if file exists or not.

Regards.

If you want to check file existance, you can use TryGetItemAsync() like this:

StorageFile sf = await ApplicationData.Current.LocalFolder.TryGetItemAsync(DB_NAME);
