Great video.

You mention in the cast that acquiring the file write signature in Page_Load isn't ideal (I agree cos only I can only get it to last for max 29 mins). Where is the best place to get the signature?

My ASP.NET Role 'is' the silverlight control that is hosts. Theres a control on the silverlight control to upload a file to Blob Storage. This is fine while the signature is valid, but not so good when it's expired

Cheers
