Vista - Vista and WCF

I've got Vista 5308 (Feb CTP) installed, Visual Studio 2005 Team System,
WinFX Runtime Feb CTP, and Orcas CTP tools. I've created a pretty simple
solution in three projects (Interface/implementation, service host, and
client). When I run the host, I get a FatalExecutionEngineException. There
is absolutely no P/Invoke, COM-interop, or anything "weird." The interface
defines a single method returning a decimal. The implementation returns the
current milliseconds from Date.Now.

I did have some trouble with the config file (ported from an earlier CTP).
I have:

<system.serviceModel>
<services>
<service name="TestService">
<endpoint address=""
binding="wsHttpBinding"
contract="Test.TimeService"/>
</service>
</services>
</system.serviceModel>

My host declares:

using( ServiceHost host = new ServiceHost(typeof(TimeService)))
{
host.Open();
...
}

Anything obvious?

Thanks!

I tried this on another computer. I had suspicions that my hardware or
configuration might be somewhat at fault. On the other computer (Vista build
5366), I get:

"CallbackException was unhandled

A user callback threw an exception. Check the exception stack and inner
exception to determine the callback that failed.

HTTP could not register URL http://+:8000/TestService/. Your process does
not have access rights to this namespace."

I should also make it clear (since my config snippet in my original message
isn't very clear), that I do have the implementation class name in the
service/@name attribute and the interface name in the
service/endpoint/@contract attribute.
