What does that mean performance-wise, calling AsEnumerable for a datatable with 5000 records ?

Marcel,

LINQ to DataSet, like all of in-memory LINQ, works on a IEnumerable. That means that the net effect of calling AsEnumerable is a low cost operation, as it only sets up the IEnumerable that the rest of the query uses. Now, if your query is expensive, then the total cost is high, but the costs will be roughly same as for a List<T> (or other in-memory structures).

Thanks,

Erick
