Access Existing SQLite database in Crossplatform solutions

Background:

I am trying to build out a crossplatform mobile solution using MVVMCross.  Stuart Lodge's N+1 series does a great job explaining how to use a new sqlite database.  The missing use case is how to implement the solution for an existing sqlite database.  I am working on that solution currently.

Problem:

My immediate issue was how to get the Windows Phone sqlite database from the installation into the app storage.

Solution:

private async Task CopyDatabase()

{

    bool isDatabaseExisting = false;

    try

    {

        StorageFile storageFile = await ApplicationData.Current.LocalFolder.GetFileAsync("people.db");

        isDatabaseExisting = true;

    }

    catch

    {

        isDatabaseExisting = false;

    }

    if (!isDatabaseExisting)

    {

        StorageFile databaseFile = await Package.Current.InstalledLocation.GetFileAsync("people.db");

        await databaseFile.CopyAsync(ApplicationData.Current.LocalFolder);

    }

}
