public System.Collections.Frozen.FrozenSet<T>.AlternateLookup<TAlternate> GetAlternateLookup<TAlternate> ();
member this.GetAlternateLookup : unit -> System.Collections.Frozen.FrozenSet<'T>.AlternateLookup<'Alternate>
Public Function GetAlternateLookup(Of TAlternate) () As FrozenSet(Of T).AlternateLookup(Of TAlternate)

Type Parameters
