Hi,

I can't quite figure out why this Linq Statement isn't working as i would expect:

    Dim distinctSurchargesList = (From thisparent As Parent In ThisParentCollection _
                                    From thisChild As Child In thisparent.theseChildren _
                                    Select New With {.childId = thischild.Id}).Distinct()

I would assume that this would create a new collection of anonymous types, that would be distinct. Instead it creates a collection the size of the "ThisParentCollection" with duplicate "MyAnonymousType" in it (duplicate id's).

Can anyone tell me where im going wrong?

Thanks
