Summary from other messages of the things you need to do:

1. Add "using System.Collections.Generic;" to the top of the file,
since that's the namespace IEnumerable<T> is in.
2. Make sure you have a reference to "System" using the "edit
references" dialog - right-click on the "references" folder in the
project tree.
3. Double-check that the target framework is 3.5
4. Add a reference to "System.Core" because this is needed for
System.Linq and the LINQ queries.
5. Fix the type name - it's "IEnumerable", not "IEnurmerable" :-)

Steps 3 & 4 shouldn't be necessary, because those are the defaults in
MD 2.1+, but it's worth checking just in case.

Note that you can also use "var query = from ..." instead of
specifying the type explicitly.
