Hello, I am trying to get the object with the highest id (integer). Here is the code:
using (var odb = OdbFactory.Open(DatabaseName))
    var humanInfoList = from humanInfo in odb.AsQueryable<HumanCandidateWrapper>()
                                orderby descending
                                select humanInfo;

    int count = humanInfoList.Count<HumanCandidateWrapper>();
    if (count > 0)
            newId = humanInfoList.First<HumanCandidateWrapper>();
The very odd thing is that this code gives "index out of range" exception on last line. When I debug I see that count variable is 1, so database has an object in it. So how come it is possible that First() method gives out of range exception? Shouldn't "count > 0" if clause protect this from out of range exception?

please rise the issue on Issue tab. If you could attach sample which is reproducing that would be great. That sounds like bug in NDatabase to Linq provider.
