NotImplementedException - The method or operation is not implemented

i jusy downloaded PowerShell CTP 2.0 and I'm fairly new to it so bare
with me please.

i'm getting a
"System.NotImplementedException
The method or operation is not implemented"

while trying the following piece of code
[System.Reflection.Assembly]::Load("System.Xml, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089")
trap [Exception]{
write-host
write-error $("TRAPPED: " + $_.Exception.GetType().FullName);
write-error $("TRAPPED: " + $_.Exception.Message);
continue;
}
$xmlDoc=new-object System.Xml.XmlDocument
$xmlDoc.PreserveWhitespace = true;
$xmlDoc.Load("D:\Stuff\Other Files\create.xml");
$xmlSignElt=$xmlDoc.GetElementsByTagName("sign") # statement on which
it's choking

...
I assume,from the exception message that the GetElementsByTagName is
not implemented in PowerShell but how come i can use other functions
from the same class this method exists in ?
Aren't all the .NET namespaces available for use inside PS scripts?
If not, how do i know which methods are available and which are not?
i'm using .NET 2.0

This should be "= $true" and not "= true". Please change and retry
and/or provide your create.xml contents for us to test if you can.

it's working now sorry my mistake, it was breaking while trying to
access the XmlNodeList , i apparently was doing it the wrong way
i'm having another exception now, first let me explain what i'm
trying to do . My target is to encypt some elements of an XML file
with an asymetric key.

if ($elementToEncrypt -eq $null){
throw (new-object System.Xml.XmlException("The specified
element was not found"))

}
$sessionKey = $null

#Create a 256 bit Rijndael key.
$sessionKey = new-object System.Security.Cryptography.RijndaelManaged
$sessionKey.KeySize = 256

$edElement = new-object System.Security.Cryptography.Xml.EncryptedData
write-host $("elementToEncrypt is null? " + ($elementToEncrypt -eq
$null))
$encryptedXml = new-object
System.Security.Cryptography.Xml.EncryptedXml
$encryptedElement = $encryptedXml.EncryptData($elementToEncrypt,
$sessionKey, $false)

write-host $("encryptedElement is null? " + ($encryptedElement -eq
$null))

$edElement.Type = $encryptedXml.XmlEncElementUrl
$edElement.Id = $EncryptionElementID


$edElement.EncryptionMethod = new-object
System.Security.Cryptography.Xml.EncryptionMethod($encryptedXml.XmlEncAES256Url);
# Encrypt the session key and add it to an EncryptedKey element.
$ek = new-object System.Security.Cryptography.Xml.EncryptedKey

[byte[]] $encryptedKey =
[System.Security.Cryptography.Xml.EncryptedXml]::EncryptKey($sessionKey.Key,
$Alg, $false);

$ek.CipherData = new-object
System.Security.Cryptography.Xml.CipherData($encryptedKey);

and the last line is giving the following error when executed
"Cannot find an overload for ".ctor" and the argument count: "128"."

by the way i had to work my brains out into finding the line spitting
the error since the error message and the StackTrace do not mention it
as far as i saw
thanks again.
Oh one more thing! Is there an editor,preferably a free one, other
than VS that i can use for writing PS scripts. I tried using the PS
Graphical editor but it's nothing more than a syntax coloring tool and
an execution environment.

Honestly, what you're doing is a bit beyond what I currently understand.

How are you defining $encryptedkey? You don't have that part in your post.
There are a few. What features are you looking for exactly?
