Things to keep in mind
• the RemoveValues function requires a “List” to be passed to it. Adding in the GUID into the RemoveValues function didn’t seem to do it.
• An example PowerShell activity that allows you to build a list of object GUIDs to pass to the Update Resources activity.

Below is how I modified it… We could probably be more elegant by add
function New-GenericObject
{
<#
.Synopsis
Create a new generic object.
.Description
Create a new generic object.
.Example
New-GenericObject -TypeName System.Collections.Generic.List -TypeParameters Microsoft.MetadirectoryServices.CSEntryChange
#>
[CmdletBinding()]
[OutputType([object])]
param(
[parameter(Mandatory = $true)]
[string]
$TypeName,
[parameter(Mandatory = $true)]
[string[]]
$TypeParameters,
[parameter(Mandatory = $false)]
[object[]]
$ConstructorParameters
)
process
{
$genericTypeName = $typeName + '`' + $typeParameters.Count
$genericType = [Type]$genericTypeName
if (!$genericType)
{
throw "Could not find generic type $genericTypeName"
}
# Bind the type arguments to it
$typedParameters = [type[]] $TypeParameters
$closedType = $genericType.MakeGenericType($typedParameters)
if (!$closedType)
{
throw "Could not make closed type $genericType"
}
# Create the closed version of the generic type, don't forget comma prefix
,[Activator]::CreateInstance($closedType, $constructorParameters)
}
}
$MembersToAdd = New-GenericObject System.Collections.Generic.List Microsoft.ResourceManagement.WebServices.UniqueIdentifier
$MembersToRemove = New-GenericObject System.Collections.Generic.List Microsoft.ResourceManagement.WebServices.UniqueIdentifier

$MembersToRemove.Add($ObjectID)
