how do i cast linc query result to ObservableCollection<>

i have the following ob collection defined :
public ObservableCollection<ServiceBundleLookup> ServiceBundles{



iwant to set it to the result of this link query :
ServiceBundles = (ObservableCollection<ServiceBundleLookup>)(from t in SBHs
                                                                                where t.ServiceBundle != null
                                                                                orderby t.ServiceBundle descending
                                                                                select new { t.ServiceBundle }).Distinct();

But am getting trhe following error :

Unable to cast object of type '<DistinctIterator>d__81`1[<>f__AnonymousType0`1[System.String]]' to type 'System.Collections.ObjectModel.ObservableCollection`1[Bnz.TTSC.Client.Entities.ServiceBundleLookup]'.

I think there are 2 issues with your code above
1. You can not get an ObservableCollection from a Linq iteration, for this change ObservableCollection to IEnumerable. If you really want ObservableCollection you can then convert by looping through each IEnumerable member.
2. the Select statement is wrong, you are creating an Anonymous type by saying Select new { t.ServiceBundle}
instead you should say Select new ServiceBundleLookup() { ServiceBundle =  t.ServiceBundle }
Where I am assuming the class  ServiceBundleLookup has a public field  ServiceBundle

Try this:

ServiceBundles = new ObservableCollection<ServiceBundleLoopup>
(
   SBHs
      .Where(t => t.ServiceBundle != null)
      .OrderByDescending(t => t.ServiceBundle)
      .Select(t => t.ServiceBundle)
      .Distinct()
);
