Using Any Constructor like a primary constructor

[TonyValenti]

Is it possible to use any constructor like a primary constructor?

I have a ton of classes that I currently have to define like this:

internal class DiaryParticipatingContact_ByDiaryId2 : LookupCache<long, DiaryParticipatingContact, DiaryParticipatingContactCache> {
    public DiaryParticipatingContact_ByDiaryId2() : base(x => x.DiaryId) {
    }
}

but I'd like to define like this:

internal class DiaryParticipatingContact_ByDiaryId1: LookupCache<long, DiaryParticipatingContact, DiaryParticipatingContactCache>
  (x => x.DiaryId) { }

Thanks for the help!

You can do

internal class DiaryParticipatingContact_ByDiaryId1() : LookupCache<long, DiaryParticipatingContact, DiaryParticipatingContactCache>
  (x => x.DiaryId);
