@annarao - Sounds like you haven't related the document library properly to your database entity. The document library cannot be a top level parent (or unrelated) in this release. It must be related to an entity from your database and be the child part of the relation. (i.e. One Customer has many Documents)
Going forward we're seeing customers ask for mobile and better business & data services support so this is why have been working on HTML5 and Office 365. I should mention that the above talk was really well received at BUILD.
Thanks all that came! It was a really fun session.
Jason, don't shoot yourself in the face, that leaves a messy keyboard.
And to be clear, I only made statements about LightSwitch in that podcast. We have been focusing on HTML client and Office 365 for a couple years now. We will support the Silverlight client as long as Silverlight itself is supported, but our innovation will happen in the HTML & Office365 going forward.
