>you can create loJobs anywhere you want. The query isn't executed until you actually use it.

It is interesting however that we can have access to the Count property even if the query hasn't been executed, thus just before the For Each loop. Because, I have this code:

Dim loJobs = (From...)

' If we have some records
If loJobs.Count > 0 Then
   ' Do something
End If

' For each record
For Each loJob In loJobs
    ' Do something
Next
