Here is a short 7 minute video to serve as an introduction to the Samples that are included with the Visual Studio Orcas March CTP. The samples that shipped with the CTP needed to be updated. As a result, its best if you don't pull them from the CTP help file, instead, download them from my blog.

This video gives you a brief introduction to the samples, and explains about the  support directories, called Data, and ObjectDumper. These directories contain files that some of the other projects rely upon. The video also shows you key samples such as SampleQueriesDynamicQuery, ExpressionTreeVisualizer and WinFormsDataBinding.

I recorded the video on my Vista laptop, and ran the samples in the Virtual PC version of the March CTP. Especially if you are running Vista, you also might enjoy using the VPC version of the CTP.
