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-before

internal bool CanPin()
{
    return !this.IsPinned()
        && this.UnderlyingModel != null
        && !this.IsRunningInKidsCorner()
        && (this.UnderlyingModel.IsSpecial
         || string.IsNullOrWhiteSpace(this.UnderlyingModel.ArtUrl)
         || (!string.IsNullOrWhiteSpace(this.UnderlyingModel.ArtUrl)
          && this.imageCacher.IsCached(this.UnderlyingModel.ArtUrl)));
}
