Kann über den Browser auf den WCF-Dienst zugreifen, aber nicht über einen GET in der PowerShell

Question

Ich habe einen WCF-Dienst eingerichtet, der über den Browser funktioniert. Er gibt das erwartete Ergebnis zurück. Nun, wenn es über Powershell zuzugreifen versuchen, erhalte ich diese Störung

Invoke-WebRequest : The underlying connection was closed: An unexpected error occurred on a send. 

Ich bin Hosting dies auf IIS als eine Anwendung, die an der Stelle des Dienstes auf meinem System verweist, genannt „ValidationServiceApp“ Also ich darauf zugreifen kann via: "https://myPc/ValidationServiceApp/RemoteService.svc/validationresult/"

Hier ist die Powershell-Code:

[Net.ServicePointManager]::ServerCertificateValidationCallback = {$true} #handle unsigned certs as its on my local machine on IIS 
$testurl = "https://myPc/ValidationServiceApp/RemoteService.svc/validationresult/" 
$result = Invoke-WebRequest -Method GET -Uri $testurl 
Write-Host $result 

der Service in VS:

IRemoteService.cs

[OperationContract] 
     [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, 
      BodyStyle = WebMessageBodyStyle.Wrapped, 
      UriTemplate = "ValidationResult/")] 
     bool ValidationResult(); 

RemoteService.svc.cs

public bool ValidationResult() 
{ 
    return true; 
    //throw new NotImplementedException(); 
}

Betrachten Sie das New-WebServiceProxy Cmdlets zu verwenden, wenn mit einem WCF-Webservice in Powershell arbeiten.

$proxy= New-WebServiceProxy -Uri "https://myPc/ValidationServiceApp/RemoteService.svc" 
# retrieve available methods: 
$proxy | Get-Member
