"(503) Server Unavailable" with call to XSL Transform in Windows Server 2008

Question

So I run this Windows Server 2008 security update and this code block is now throwing an error:

using(MemoryStream ms = new MemoryStream())
{
    xslt.Transform(navigableSet, xslArgs, ms);
    ms.Position = 0;
    ret = new XPathDocument(ms);
}
return ret;

The error is EXCEPTION [System]: The remote server returned an error: (503) Server Unavailable. I assume that this is Windows Server 2008 making shared memory super-secure. This means that I'll need to obtain IO permissions---right?

Answer 1

Sadly, this my solution:

using(MemoryStream ms = new MemoryStream())
{
    XmlReader reader = XmlReader.Create(new StringReader(SomeXmlString));
    XmlWriter writer = XmlWriter.Create(ms);
    xslt.Transform(reader, xslArgs, writer, null); //Passing null here prevents resolving...
    ms.Position = 0;
    ret = new XPathDocument(ms);
}

Rasmus Faber had a similar problem about a year ago. My apologies for wasting time! I could just fiddle with Windows Server 2008 Firewall stuff to open up whatever closed but my code needs to be more explicit about making such calls in the first place!
