How use system.tuple in powershell? - powershell

Question

Just for curiosity, it's not a 'I must have it', but how declare a tuple using system.tuple class in powershell?
I'm using powershell.exe.config to load framework 4.0 but I'm not able to create a tuple.
Trying this:
PS C:\ps1> $a = [System.Tuple``2]::Create( "pino", 34)
Chiamata al metodo non riuscita. [System.Tuple`2] non contiene un metodo denominato 'Create'.
In riga:1 car:31
+ $a = [System.Tuple``2]::Create <<<< ( "pino", 34)
+ CategoryInfo : InvalidOperation: (Create:String) [], RuntimeException
+ FullyQualifiedErrorId : MethodNotFound
sorry for Italian sample...
Thank you for help.
EDIT:
if i try:
PS C:\ps1> $a = [System.Tuple]::Create(34,"pino")
Impossibile trovare un overload per "Create" e il numero di argomenti: "2".
In riga:1 car:28
+ $a = [System.Tuple]::Create <<<< (34,"pino")
+ CategoryInfo : NotSpecified: (:) [], MethodException
+ FullyQualifiedErrorId : MethodCountCouldNotFindBest

Here is a way
PS> $a = New-Object 'Tuple[string,int]'("Jack", 78)
PS> $a
Item1 Item2
----- -----
Jack 78
Another one
PS> $dpt = New-Object 'Tuple[string,string,int]'("Cantal", "Aurillac", 15)
PS> $dpt.Item2
Aurillac

Recall
to see which CLR you are using, just use $PSVersionTable
PS C:\> $PSVersionTable
Name Value
---- -----
CLRVersion 2.0.50727.4959
BuildVersion 6.1.7600.16385
PSVersion 2.0
WSManStackVersion 2.0
PSCompatibleVersions {1.0, 2.0}
SerializationVersion 1.1.0.1
PSRemotingProtocolVersion 2.1
if you want PowerShell to start using CLR 4.0 you have to put the file powershell.exe.config in the folder $PSHOME (C:\Windows\System32\WindowsPowerShell\v1.0)
powershell.exe.config :
<?xml version="1.0"?>
<configuration>
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0.30319"/>
<supportedRuntime version="v2.0.50727"/>
</startup>
</configuration>
Result :
