Simply put, with the update of SubSonic 2.1 (Beta), use of Find( delegate ) no longer works.  The inheritance chain was changed to Collection<T> from List<T> for data binding objectives.  No worries, the underlying collection is there for you!  You can get List functionality from Ling extensions.

Code that was broken by the update:

Store.Image imageMoved = imageCollection.Find(delegate(Store.Image image) {

  return image.ImageId == imageId;

});

Error    5    Cannot convert anonymous method to type ‘object’ because it is not a delegate type    C:\…\Source\Web\admin\controls\product\images.ascx.cs    226    59    Web

The Find method is now replaced and we need to change the above to the following.

using System.Linq;

...

Store.Image imageMoved = imageCollection.ToList<Store.Image>().Find(delegate(Store.Image image) {

  return image.ImageId == imageId;

});
