ASP.NET

It seems like ASP.NET WebMethods are not "web servicey" enough to work with New-WebServiceProxy. Or maybe it is, and I haven't figured out how to initialize it?

So instead, I tried doing it manually, like so:

$wc = new-object System.Net.WebClient
$wc.Credentials = [System.Net.CredentialCache]::DefaultCredentials

$url = "http://www.domenicdenicola.com/AboutMe/SleepLog/default.aspx/GetSpans"
$postData = "{`"starting`":`"\/Date(1254121200000)\/`",`"ending`":`"\/Date(1270018800000)\/`"}"
$result = $wc.UploadString($url, $postData)

But this gives me "The remote server returned an error: (500) Internal Server Error." So I must be doing something slightly wrong.

Any ideas on how to call my PageMethod from PowerShell, and not get an error?
