Execute a one-way wcf service operation from powershell

Question

I have a scheduled task which executes a powershell script every hour. The powershell script must make a call to a one-way WCF service operation. Essentially it just needs to

I like jdmichal's answer because it is intuitive to make it work for inputs where the parameters are objects... the code required some modifications, this is what worked for me:

[Reflection.Assembly]::LoadFrom("C:\.....\WcfService2.dll")
[Reflection.Assembly]::LoadWithPartialName("System.ServiceModel")

$httpBinding = New-Object System.ServiceModel.BasicHttpBinding
if($useNTLM){
    #passes the default creds
    $httpBinding.Security.Mode = "TransportCredentialOnly"
    $httpBinding.Security.Transport.ClientCredentialType = "Ntlm"
}
$endpointAddress = New-Object System.ServiceModel.EndpointAddress 'http://localhost:63600/Service1.svc'

$contractDescription = [System.ServiceModel.Description.ContractDescription]::GetContract([WcfService2.IService1])

$serviceEndpoint = New-Object System.ServiceModel.Description.ServiceEndpoint($contractDescription, $httpBinding, $endpointAddress)
$channelFactory = New-Object "System.ServiceModel.ChannelFactory``1[WcfService2.IService1]"($serviceEndpoint)

$webProxy = $channelFactory.CreateChannel();
$result = $webProxy.GetData(123);
Write-Output $result #prints 123
$comptype = new-object WcfService2.CompositeType
$comptype.BoolValue =$false
$comptype.StringValue = "whatever123zxcv"
$result = $webProxy.GetDataUsingDataContract($comptype);
Write-Output $result #prints whatever123zxcv

UPDATE: I've found out how to use composite objects with the New-WebServiceProxy cmdlet (thanks to http://www.sqlmusings.com/2012/02/04/resolving-ssrs-and-powershell-new-webserviceproxy-namespace-issue/)

$wsProxy = New-WebServiceProxy -uri http://localhost:63600/Service1.svc
$wsProxy.UseDefaultCredentials = $true
$namespace = $wsProxy.GetType().Namespace
$myct = New-Object "$namespace.CompositeType"
$myct.BoolValue = $true;
$myct.StringValue = "asdfasdg";

$wsProxy.GetDataUsingDataContract($myct)
$wsProxy.GetData(123,$true)
