Tim Sneath [via Lamont] shows off the new Video.Show reference application:
Video.Show is an end-to-end solution that provides a reference-quality sample for user-generated video content sites. Taking advantage of all of our latest technologies: .NET Framework 3.5, ASP.NET AJAX, LINQ, Silverlight, Expression Encoder and 
Silverlight Streaming, Video.Show provides support for uploading, encoding, tagging, viewing and commenting on videos.
I was especially interested to see how they wrote the Linq data layer since it is shared out as a service. My own recent experience with this (which I will be sharing shortly) was that it was a little difficult to do. I was happy to see that the approach I took was the same as the one Vertigo took. You end up creating a set of objects that you pass outside of the service layer which are almost replicas of the Linq objects that get generated out of the database.
Overall it looks like a great reference app. Lots of code to look at and digest. You can download the bits here.
