Some time back I provided this post on how to use the 2010 Information Worker Demonstration and Evaluation Virtual Machine (RTM) to setup a SharePoint and Office 2010 development environment. In this new SharePoint Sideshow video on Channel 9, Paul and I walk through the process and we also include some tips along the way. So check out the video and get yourself setup for Office development in a separate, isolated environment (i.e. from your daily use environment) where you can create snapshots for rollback, etc. and experiment. And remember all the Office 2010 and SharePoint 2010 Channel 9 Learning Course hands-on labs are built to work on this virtual machine!
