So I feel dumb but if I run

cls

$results = [System.Collections.Generic.List[object]]@() 

$results.Add( [PSCustomObject]@{
    Name = 'John'
    Age  = 42
})

$results.add( [PSCustomObject]@{
    Name = 'John'
    Age  = 42
})

$results.Add( [PSCustomObject]@{
    Name = 'Thomas'
    Age  = 30
})

$results | Export-CSV C:\temp\test.csv

In SharePoint 2010 Management Shell it returns:

TYPESystem.Collections.Hashtable"IsReadOnly","IsFixedSize","IsSynchronized","Keys","Values","SyncRoot","Count" "False","False","False","System.Collections.Hashtable KeyCollection","System.Collections.Hashtable ValueCollection","System.Object","2"
"False","False","False","System.Collections.Hashtable KeyCollection","System.Collections.Hashtable ValueCollection","System.Object","2" "False","False","False","System.Collections.Hashtable KeyCollection","System.Collections.Hashtable ValueCollection","System.Object","2"

But if I run the code on the same machine using the ISE I get

#TYPE System.Management.Automation.PSCustomObject
"Name","Age"
"John","42"
"John","42"
"Thomas","30"

Can someone enlighten me? Sorry, I know it is a dumb question since we are moving to 2016 but I want to know why.

Do I need to include System.Management.Automation when using it via SP2010 Management Shell?
