Register a device on UPnP with C# using the Device Host API : Value does not fall within the expected range.

Question

Hi,

I'm trying to use the MS Device Host API, to register a device.

I've imported the COM component(the host one), and have the following code:

//Main code
IUPnPRegistrar registrar = (IUPnPRegistrar)new UPnPRegistrarClass();
String description = GetDescription();
String path = GetPath();
string registerDevice = registrar.RegisterDevice(description, "UPnPHosterTester.DeviceControl", "Init", "Container", path, 1800);
//sub methods
private string GetPath()
{
	return Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
}

private string GetDescription()
{
	string xml = File.OpenText("DeviceDescription.xml").ReadToEnd();
	xml = xml.Replace("@@UDN@@", "uuid:" +Guid.NewGuid().ToString());
	return xml;
}

It read an xml file:

<?xml version="1.0" encoding="utf-8" ?>
<root xmlns="urn:schemas-upnp-org:device-1-0">
	<specVersion>
		<major>1</major>
		<minor>1</minor>
	</specVersion>
	<device>
		<UDN>@@UDN@@</UDN>
		<friendlyName>Test device</friendlyName>
		<deviceType>urn:test-com:device:HostDevice:1</deviceType>
		<manufacturer>Test</manufacturer>
		<modelName>Test model name</modelName>
	</device>
</root>

My problem is that when I try to register it, I got this error: 

System.ArgumentException was unhandled
  Message=Value does not fall within the expected range.

I'm searching what I'm doing wrong since two days, and I don't find any example code for c#. This exception isn't very explicit(and the 1800 is in the range).

So what could have I done wrong?
