<p>Has anyone had any luck of using Oracle from .Net on a 64 bit machine, and using the UDT capabilities of Oracle?</p>

<p>I've been able to use an x64 ODP.Net client, but cannot find one with any support for UDTs.</p>

<p>Thanks</p>

<p>[Edit]
I've posted an answer below. The latest (as of December 2008) release is 11.1.0.7. This has support for 64 bit and UDT.</p>
