DESCRIPTION

As a result of changing the collection of context items from List<MetaItem> to IList<MetaItem>, the methods that are part of the List class and not the IList interface are no longer available. Examples include RemoveAll<>, Sort<>, etc.

SOLUTION

We have create a helper class with extension methods for backward compatibility. Please find the class attached. If you add it to the project containing your OpenAccessContext implementation, the methods will become available and your legacy code will compile.
