• File PS2WCF.ps1 — part of check-in [052c322375] at 2018-06-10 13:22:27 on branch trunk — 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.

.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

.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.Echo("Justin Dearing");

	[Parameter(ParameterSetName='WsdlUrl', Position=0, Mandatory=$true, ValueFromPipeline=$true)][string] $wsdlUrl, 
	[string] $proxyPath
) {
	switch ($PsCmdlet.ParameterSetName)
	{
		"WsdlUrl" {
			$wsdlImporter = Get-WsdlImporter -wsdlUrl $wsdlUrl
			trap [Exception]
			{
				$script:wsdlImporter = Get-WsdlImporter -wsdlUrl $wsdlUrl -httpGet $true
				continue
			}
			break
		}
	}
  $proxyType = Get-WcfProxyType $wsdlImporter
