Just a quick question, If I have an object that exposses a collection (EntityCollection) of related objects is it ok to access fileds via index, rather then casting each object in collection to a entity type to access the field.

entity.Group(idx).Fields(GroupFieldIndex.DimensionId).CurrentValue

vs.

DirectCast(entity.Group(idx),GroupEntity).DimensionId

Or, is there a way to have strongly typed collection (GroupCollection vs. EntityCollection)?

If you are using the SelfServicing scenario, then you will get strongly typed collections out of the box. But in Adapter scenario, you should cast EntityCollection items to their corresponding Entity Type.

However in .NET 2 using generics, you can have stronglyTypes collections
