OpenNETCF is in the midst of some major infrastructure updates to get automated unit testing of device assemblies working with Team Foundation Server. Let's just say that it's nowhere near a simple task.
As part of the work, we needed to automate access to the Device Emulator using the
Microsoft-supplied Automation Interfaces. Their C++ and WScript samples for usage leave a bit to be desired, so we wrapped them in an object-oriented model to provide at least a skeletal framework for launching, resetting, saving state etc. The classes haven't been heavily tested and the test harness for the classes is very basic, but it's a good starting point, and the download (below) is what we're using in our continuous integration process, so it's definitely functional.

We're releasing this source under
the MIT X-11 license. If you make updates and want to submit them back to us, we'll be happy to integrate them, but it's not required.
