Can Compact WCF be extended for duplex communication?

[Michael Wohltman]

I am trying to confirm whether duplex communication is at all possible using
..NET Compact Framework support for WCF. Our Windows CE device is not a
mobile device and I would think some sort of duplex communication should be
supported. However, I see where only basic http & custom bindings are
supported. Basic Http obviously won't meet my needs, but I also don't even
see how custom bindings can help me. I would need to write a custom channel,
but it doesn't seem that will meet my goals either. ChannelBase is supported
by the Compact Framework, however IDuplexChannel is not.

I guess I'm looking for comfirmation ( positive or negative) on whether
Compact WCF can be extended to support duplex communication w/ a device
running Windows CE.

Thanks,
-Mike

I know they're working on an exchange based duplex channel. There are also
3rd party tcp channels that support full duplex. I also remember someone
telling me about a full duplex http channel that uses 2 ports and polling...
Not sure though where I have seen them I believe they demoed it during a
DSL tolkit / Web Service Software Factory training I attended in November.
