title: System.Net.WebRequest not presenting my certificate
body: <p>Below is a snippet of code I have written to make a SOAP request to an internal Web Service we have.  If I run this with Fiddler running Fiddler alerts that the site is requesting a cert.  If I provide the cert to Fiddler this runs perfectly.  If I turn off Fidler then I get an error that the connection was closed.  I am beating my head against the wall because I am adding the cert to the ClientCertificates collection, and when I debug it I can see that it has it.  Any ideas why it is not presenting it at run time?  (you will see where I have tested with grabbing it from the local machine store and creating it from the file, and neither option is working)</p>
  
  <pre><code>            $cert = [System.Security.Cryptography.X509Certificates.X509Certificate2]::CreateFromCertFile($certPath)
              #$cert = get-item cert:\LocalMachine\* | get-ChildItem | Where-Object -FilterScript {($_.FriendlyName -eq "HRSYS")}
              $soapWebRequest = [System.Net.WebRequest]::Create($url)
              $soapWebRequest.ClientCertificates.Add($cert)
              $soapWebRequest.Headers.Add("SOAPAction", "http://service.wellsfargo.com/provider/hr/entity/teamMemberData/getTeamMemberProfileById/2010/12/") 
              $soapWebRequest.ContentType = "text/xml;charset=`"utf-8`"" 
              $soapWebRequest.Accept = "text/xml" 
              $soapWebRequest.Method = "POST" 
              $soapWebRequest.Timeout = 60000
              $soapWebRequest.UseDefaultCredentials = $true
  </code></pre>
