On low spec WP8 devices we had an issue where the UI option to create a secondary tile wasn't always being enabled properly. After identifying the most likely cause as the `CanPin()` method I had to refactor it to make it debuggable and in doing so made the binding/timing issue go away (solved it).

CanPin-after

internal bool CanPin()
{
    if (this.IsPinned())
    {
        Debug.WriteLine("Cannot pin as already pinned");
        return false;
    }

    if (this.UnderlyingModel == null)
    {
        Debug.WriteLine("Cannot pin as don't have the underlying model (needed when generating the image and deep link path)");
        return false;
    }

    if (this.IsRunningInKidsCorner())
    {
        Debug.WriteLine("Cannot pin as running in kids corner");
        return false;
    }

    if (this.UnderlyingModel.IsSpecial)
    {
        Debug.WriteLine("CAN pin as is special (will use special artwork)");
        return true;
    }

    if (string.IsNullOrWhiteSpace(this.UnderlyingModel.ArtUrl))
    {
        Debug.WriteLine("CAN pin as has no artwork (default/fallback will be used)");
        return true;
    }

    if (this.imageCacher.IsCached(this.UnderlyingModel.ArtUrl))
    {
        Debug.WriteLine("CAN pin as artwork has been cached");
        return true;
    }

    Debug.WriteLine("Cannot pin as all tests failed");
    return false;
}
