Dynamic Data Store : The saga of the missing methods
If I received 1 Swedish Crown for every time someone asked or complained about why the DDS does not implement FirstOrDefault() in its Linq stack (along with First(), Last() and LastOrDefault()) then I would have at least 40 Swedish Crowns and would retire to the Bahamas (or Västerås)
The truth is that these methods return a single item as opposed to an IEnumerable and therefore require a whole new implementation path. In an ideal world this would have been done for CMS 6 but unfortunately wasn’t. Until it is done there is a very easy workaround.
See Jonas Bergqvist’s workaround here which uses Take and Reverse to achieve the same goals.
