Not that I have not tried this in the past, but when I bought a brand new computer two weeks ago, it came with Windows Vista installed. Even though I am using this machine frequently for software development, and I have had interesting experiences last year on a laptop machine running Windows Vista for one single day after downgrading to Windows XP, I am now much more positive about running Windows Vista. So far I have not encountered problems with this new desktop machine. Honestly I have to admit that I am not installing lots of development environments side-by-side. This machine is currently only running Visual Studio 2008, but I have been able to create smart device applications with no problems. Thanks to Virtual PC, I have also installed Visual Studio 2005 with Platform Builder 6.0. This Virtual PC image is still running Windows XP, but it is running smoothly, especially thanks to the fact that this new PC has tons more processing power than my previous one. Creating Windows Embedded CE 6.0 R2 (don’t you love these long product names?) images inside a Virtual PC works fine, especially when targeting the device emulator, which I usually do. What I have not tried so far is actually trying to download an image to a real device. Thanks to the fact that Virtual PC can use a physical network card, this should not be a problem either I guess. You can find proof that my new PC is running Windows Vista together with Visual Studio 2008 smoothly, since I already presented a webcast in this new environment. Funny enough, my hardware did not cause any problems, but my phone line dropped halfway through the webcast. If you want to see Windows Vista and Visual Studio 2008 in action and if you are interested in Unit Testing for Devices, you can go here to view / download this webcast.
