Visual Studio 2010 Config Transformations TransformXml task failure

So I got a little bit inspired the other day after watching Scott Hanselman’s Web Deployment Made Awesome: If You're Using XCopy, You're Doing It Wrong from MIX10.

Here’s a summary of what I found interesting and what I see is significant for the technologies involved. It’s by no means a comprehensive review – one look at the sessions list will confirm that – but it’s what jumped out and got me excited.

Request Validation, DotNetNuke and design utopia

It’s a hot summer day in Perth over on the western seaboard of Australia and the local pub is packed with patrons downing cold beers. You’re in your shiny new Ferrari – red, of course – and come cruising past the pub in full view of the enthralled audience. As any red-blooded, testosterone fuelled Aussie bloke would do, you give the Italian thoroughbred a full redline launch to the delight of the crowd. Right up until you run into the street sign:
