Linq Query not returning IEnumerable

Question

I have the follow Linq query that is in a web application that was converted from .NET 1.1 to 3.5:

dim objListOfFilteredDataRows = from datarows as datarow in objDataSet.tables(0).rows _
                                where datarows("SomeColumn") = SomeValue

I have the exact same query in an application that was created using .NET 3.5 and the query returns an IEnumerable. However the query in the converted application is returning:

{Name = "WhereEnumerableIterator`1" FullName = "System.Linq.Enumerable+WhereEnumerableIterator`1[[System.Data.DataRow, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]"}

**Edit: When I highlight the expression, the intellisense says that it doesn't know the type of objListOfFilteredDataRows and assumes its a type of "Object".

Why is the type not infered in the converted 1.1 application but is infered in the "native" 3.5?**

What am I missing here? How do I convert the "WhereEnumeratorIterator`1 to an IEnumerable? Thanks!

Answer 1

No, you really did get an IEnumerable. It just happens to be implemented by a class inside the System.Linq.Enumerable namespace, a private class. That's unavoidable, there is no way to create an instance of an interface. Don't let the debugger info put you on the wrong track.
