# description: Call WCF Services with PowerShell using any binding. Generates proxy on the fly without needing any tool expect .NET 3.5. You can also discover the service endpoints, bindings and contracts. Read more on my blog: http://www.ilovesharepoint.com/2008/12/call-wcf-services-with-powershell.html

.SYNOPSIS
Get metadata of a service
.DESCRIPTION
Parses a wsdl or mex and generates a WsdlImporter object from it.
.EXAMPLE
Get-WsdlImporter 'http://localhost.fiddler:14232/EchoService.svc/mex'
.EXAMPLE
Get-WsdlImporter 'http://localhost.fiddler:14232/EchoService.svc' -HttpGet
.EXAMPLE
Get-WsdlImporter 'http://localhost.fiddler:14232/EchoService.svc?wsdl' -HttpGet
#>
function global:Get-WsdlImporter([CmdletBinding()][Parameter(Mandatory=$true, ValueFromPipeline=$true)][string]$WsdlUrl, [switch]$HttpGet)
{
if($HttpGet)
{
$local:mode = [System.ServiceModel.Description.MetadataExchangeClientMode]::HttpGet
}

}

.SYNOPSIS
Generate wcf proxy types
.DESCRIPTION
Examines a web services meta data (wsdl or mex) and generates the types for the client proxy,
as well as request and response contracts.
.EXAMPLE
$proxyType = Get-WcfProxyType $wsdlImporter
$endpoints = $wsdlImporter.ImportAllEndpoints();
$proxy = New-Object $proxyType($endpoints[0].Binding, $endpoints[0].Address);
#>

.SYNOPSIS
Generate wcf proxy
.DESCRIPTION
Generate wcf proxy in a manner similar to a Get-WebServiceProxy
.EXAMPLE
$proxy = Get-WcfProxy 'http://localhost.fiddler:14232/EchoService.svc/mex'
$proxy.Echo("Justin Dearing");
.EXAMPLE
$proxy = Get-WcfProxy 'net.tcp://localhost:8732/EchoService/mex' 'net.tcp://localhost:8732/EchoService/' (New-Object System.ServiceModel.NetTcpBinding)
$proxy.Echo("Justin Dearing");
